Navigating the dense urban canyons of cities like San Francisco or New York can be a nightmare for GPS systems. The towering skyscrapers block and reflect satellite signals, leading to location errors of tens of meters. For you and me, that might mean a missed turn. But for an autonomous vehicle or a delivery robot, that level of imprecision is the difference between a successful mission and a costly failure. These machines require pinpoint accuracy to operate safely and efficiently. Addressing this critical challenge, researchers from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have introduced a groundbreaking new method for visual localization during CVPR 2025 Their new paper, “FG2: Fine-Grained Cross-View Localization by Fine-Grained Feature Matching,” presents a novel AI model that significantly enhances the ability of a ground-level system, like an autonomous car, to determine its exact position and orientation using only a camera and a corresponding aerial (or satellite) image. The new approach has demonstrated a remarkable 28% reduction in mean localization error compared to the previous state-of-the-art on a challenging public dataset. Key Takeaways: Superior Accuracy: The FG2 model reduces the average localization error by a significant 28% on the VIGOR cross-area test set, a challenging benchmark for this task. Human-like Intuition: Instead of relying on abstract descriptors, the model mimics human reasoning by matching fine-grained, semantically consistent features—like curbs, crosswalks, and buildings—between a ground-level photo and an aerial map. Enhanced Interpretability: The method allows researchers to “see” what the AI is “thinking” by visualizing exactly which features in the ground and aerial images are being matched, a major step forward from previous “black box” models. Weakly Supervised Learning: Remarkably, the model learns these complex and consistent feature matches without any direct labels for correspondences. It achieves this using only the final camera pose as a supervisory signal. Challenge: Seeing the World from Two Different Angles The core problem of cross-view localization is the dramatic difference in perspective between a street-level camera and an overhead satellite view. A building facade seen from the ground looks completely different from its rooftop signature in an aerial image. Existing methods have struggled with this. Some create a general “descriptor” for the entire scene, but this is an abstract approach that doesn’t mirror how humans naturally localize themselves by spotting specific landmarks. Other methods transform the ground image into a Bird’s-Eye-View (BEV) but are often limited to the ground plane, ignoring crucial vertical structures like buildings. FG2: Matching Fine-Grained Features The EPFL team’s FG2 method introduces a more intuitive and effective process. It aligns two sets of points: one generated from the ground-level image and another sampled from the aerial map. Here’s a breakdown of their innovative pipeline: Mapping to 3D: The process begins by taking the features from the ground-level image and lifting them into a 3D point cloud centered around the camera. This creates a 3D representation of the immediate environment. Smart Pooling to BEV: This is where the magic happens. Instead of simply flattening the 3D data, the model learns to intelligently select the most important features along the vertical (height) dimension for each point. It essentially asks, “For this spot on the map, is the ground-level road marking more important, or is the edge of that building’s roof the better landmark?” This selection process is crucial, as it allows the model to correctly associate features like building facades with their corresponding rooftops in the aerial view. Feature Matching and Pose Estimation: Once both the ground and aerial views are represented as 2D point planes with rich feature descriptors, the model computes the similarity between them. It then samples a sparse set of the most confident matches and uses a classic geometric algorithm called Procrustes alignment to calculate the precise 3-DoF (x, y, and yaw) pose. Unprecedented Performance and Interpretability The results speak for themselves. On the challenging VIGOR dataset, which includes images from different cities in its cross-area test, FG2 reduced the mean localization error by 28% compared to the previous best method. It also demonstrated superior generalization capabilities on the KITTI dataset, a staple in autonomous driving research. Perhaps more importantly, the FG2 model offers a new level of transparency. By visualizing the matched points, the researchers showed that the model learns semantically consistent correspondences without being explicitly told to. For example, the system correctly matches zebra crossings, road markings, and even building facades in the ground view to their corresponding locations on the aerial map. This interpretability is extremenly valuable for building trust in safety-critical autonomous systems. “A Clearer Path” for Autonomous Navigation The FG2 method represents a significant leap forward in fine-grained visual localization. By developing a model that intelligently selects and matches features in a way that mirrors human intuition, the EPFL researchers have not only shattered previous accuracy records but also made the decision-making process of the AI more interpretable. This work paves the way for more robust and reliable navigation systems for autonomous vehicles, drones, and robots, bringing us one step closer to a future where machines can confidently navigate our world, even when GPS fails them.

There is an inherent problem with the design of shower heads. Not some of them, all of them. The problem is that their very design creates the ideal circumstances for mold to thrive within them, internally, in areas that you cannot access for cleaning.A bathtub faucet or kitchen sink tap is simply just a shaped pipe that allows water to flow through them. When you turn the water off, the pipe mouths quickly dry, thanks to their relatively wide shape and local airflow.Showerheads, however, are complex workings of intricate inner channels and nozzles, designed to break the water flow into spray patterns that end users find desirable. These channels are all inside the showerhead and get little airflow. The channels can never really dry out completely, and over time, that interal dampness allows bacteria and mold—including the dreaded black mold--to thrive. In this shot of a showerhead that has been cut open by a saw, a lot of what you see is the detritus of the cut plastic, but you can also see the brown stuff. And deeper inside the head, you find this: The mother of Steve Sunshine, an inventor, was suffering from respiratory issues. Sunshine disassembled her showerhead and found it was filled with mold. He subsequently designed this ShowerClear: This ingenious design pops open, so that after a shower you can let the shower head's innards dry out. It also makes it easy to clean, so you can eliminate mineral build-up. (This eliminates the mild hassle that many of us undertake to clean our showerheads, which is soaking them in a vessel filled with vinegar for a few hours.) The ShowerClear heads come in a variety of finishes and run $140.

In Brief Posted: 10:54 AM PDT · June 14, 2025 Image Credits:Mario Tama / Getty Images Waymo limits service ahead of today’s ‘No Kings’ protests Alphabet-owned robotaxi company Waymo is limiting service due to Saturday’s scheduled nationwide “No Kings” protests against President Donald Trump and his policies. A Waymo spokesperson confirmed the changes to Wired on Friday. Service is reportedly affected in San Francisco, Austin, Atlanta, and Phoenix, and is entirely suspended in Los Angeles. It’s not clear how long the limited service will last. As part of protests last weekend in Los Angeles against the Trump administration’s immigration crackdown, five Waymo vehicles were set on fire and spray painted with anti-Immigration and Customs Enforcement (ICE) messages. In response, Waymo suspended service in downtown LA. While it’s not entirely clear why protestors targeted the vehicles, they may be seen as a surveillance tool, as police departments have requested robotaxi footage for their investigations in the past. (Waymo says it challenges requests that it sees as overly broad or lacking a legal basis.) According to the San Francisco Chronicle, the city’s fire chief told officials Wednesday that “in a period of civil unrest, we will not try to extinguish those fires unless they are up against a building.” Topics

DJI Osmo Action 4. Adrian Kingsley-Hughes/ZDNETMultiple DJI Osmo Action 4 packages are on sale at Amazon. Both the Essential and Standard Combos have been discounted to $249, while the Adventure Combo has dropped to $349.DJI might not be the first name on people's lips when it comes to action cameras, but the company that's better known for its drones also has a really solid line of action cameras. And its latest device, the Osmo Action 4 camera, has some very impressive tricks up its sleeve.Also: One of the most versatile cameras I've used is not from Sony or Canon and it's on saleSo, what sets this action camera apart from the competition? Let's take a look. details View at Amazon First off, this is not just an action camera -- it's a pro-grade action camera.From a hardware point of view, the Osmo Action 4 features a 1/1.3-inch image sensor that can record 4K at up to 120 frames per second (fps). This sensor is combined with a wide-angle f/2.8 aperture lens that provides an ultra-wide field of view of up to 155°. And that's wide. Build quality and fit and finish are second to none. Adrian Kingsley-Hughes/ZDNETFor when the going gets rough, the Osmo Action 4 offers 360° HorizonSteady stabilization modes, including RockSteady 3.0/3.0+ for first-person video footage and HorizonBalancing/HorizonSteady modes for horizontal shots. That's pro-grade hardware right there.Also: This new AI video editor is an all-in-one production service for filmmakers - how to try itThe Osmo Action 4 also features a 10-bit D-Log M color mode. This mode allows the sensor to record over one billion colors and offers a wider dynamic range, giving you a video that is more vivid and that offers greater detail in the highlights and shadows. This mode, combined with an advanced color temperature sensor, means that the colors have a true-to-life feel regardless of whether you're shooting outdoors, indoors, or even underwater. The DJI Osmo Action 4 ready for action. Adrian Kingsley-Hughes/ZDNETI've added some video output from the Osmo Action 4 below. There are examples in both 1080p and 4K. To test the stabilization, I attached the camera to the truck and took it on some roads, some of which are pretty rough. The Osmo Action 4 had no problem with that terrain. I also popped the camera into the sea, just because. And again, no problem.I've also captured a few time-lapses with the camera -- not because I like clouds (well, actually, I do like clouds), but pointing a camera at a sky can be a good test of how it handles changing light. Also: I recommend this action camera to beginners and professional creators. Here's whyTimelapses with action cameras can suffer from unsightly exposure changes that cause the image to pulse, a condition known as exposure pumping. This issue can also cause the white balance to change noticeably in a video, but the Osmo Action 4 handled this test well.All the footage I've shot is what I've come to expect from a DJI camera, whether it's from an action camera or drone -- crisp, clear, vivid, and also nice and stable.The Osmo Action 4 is packed with various electronic image-stabilization (EIS) tech to ensure that your footage is smooth and on the horizon. It's worth noting the limitations of EIS -- it's not supported in slow-motion and timelapse modes, and the HorizonSteady and HorizonBalancing features are only available for video recorded at 1080p (16:9) or 2.7K (16:9) with a frame rate of 60fps or below. On the durability front, I've no concerns. I've subjected the Osmo Action 4 to a hard few days of testing, and it's not let me down or complained once. It takes impacts like a champ, and being underwater or in dirt and sand is no problem at all. Also: I'm a full-time Canon photographer, but this Nikon camera made me wonder if I'm missing outYou might think that this heavy-duty testing would be hard on the camera's tiny batteries, but you'd be wrong. Remember I said the Osmo Action 4 offered hours of battery life? Well, I wasn't kidding.  The Osmo Action 4's ultra-long life batteries are incredible.  Adrian Kingsley-Hughes/ZDNETDJI says that a single battery can deliver up to 160 minutes of 1080p/24fps video recording (at room temperature, with RockSteady on, Wi-Fi off, and screen off). That's over two and a half hours of recording time. In the real world, I was blown away by how much a single battery can deliver. I shot video and timelapse, messed around with a load of camera settings, and then transferred that footage to my iPhone, and still had 16% battery left.No action camera has delivered so much for me on one battery. The two extra batteries and the multifunction case that come as part of the Adventure Combo are worth the extra $100. Adrian Kingsley-Hughes/ZDNETAnd when you're ready to recharge, a 30W USB-C charger can take a battery from zero to 80% in 18 minutes. That's also impressive.What's more, the batteries are resistant to cold, offering up to 150 minutes of 1080p/24fps recording in temperatures as low as -20°C (-4°F). This resistance also blows the competition away.Even taking into account all these strong points, the Osmo Action 4 offers even more.The camera has 2x digital zoom for better composition, Voice Prompts that let you know what the camera is doing without looking, and Voice Control that lets you operate the device without touching the screen or using the app. The Osmo Action 4 also digitally hides the selfie stick from a variety of different shots, and you can even connect the DJI Mic to the camera via the USB-C port for better audio capture.Also: Yes, an Android tablet finally made me reconsider my iPad Pro loyaltyAs for price, the Osmo Action 4 Standard Combo bundle comes in at $399, while the Osmo Action 4 Adventure Combo, which comes with two extra Osmo Action Extreme batteries, an additional mini Osmo Action quick-release adapter mount, a battery case that acts as a power bank, and a 1.5-meter selfie stick, is $499.I'm in love with the Osmo Action 4. It's hands down the best, most versatile, most powerful action camera on the market today, offering pro-grade features at a price that definitely isn't pro-grade.  Everything included in the Action Combo bundle.

Elon Musk may be gone from the Trump administration — and his friendship status with President Donald Trump may be at best uncertain — but his whirlwind stint in government certainly left its imprint. The Department of Government Efficiency (DOGE), his pet government-slashing project, remains entrenched in Washington. During his 130-day tenure, Musk led DOGE in eliminating about 260,000 federal employee jobs and gutting agencies supporting scientific research and humanitarian aid. But to date, DOGE claims to have saved the government $180 billion — well short of its ambitious (and frankly never realistic) target of cutting at least $2 trillion from the federal budget. And with Musk’s departure still fresh, there are reports that the federal government is trying to rehire federal workers who quit or were let go. For Elaine Kamarck, senior fellow at the Brookings Institution, DOGE’s tactics will likely end up being disastrous in the long run. “DOGE came in with these huge cuts, which were not attached to a plan,” she told Today, Explained co-host Sean Rameswaram. Kamarck knows all about making government more efficient. In the 1990s, she ran the Clinton administration’s Reinventing Government program. “I was Elon Musk,” she told Today, Explained. With the benefit of that experience, she assesses Musk’s record at DOGE, and what, if anything, the billionaire’s loud efforts at cutting government spending added up to. Below is an excerpt of the conversation, edited for length and clarity. There’s much more in the full podcast, so listen to Today, Explained wherever you get podcasts, including Apple Podcasts, Pandora, and Spotify. What do you think Elon Musk’s legacy is? Well, he will not have totally, radically reshaped the federal government. Absolutely not. In fact, there’s a high probability that on January 20, 2029, when the next president takes over, the federal government is about the same size as it is now, and is probably doing the same stuff that it’s doing now. What he did manage to do was insert chaos, fear, and loathing into the federal workforce. There was reporting in the Washington Post late last week that these cuts were so ineffective that the White House is actually reaching out to various federal employees who were laid off and asking them to come back, from the FDA to the IRS to even USAID. Which cuts are sticking at this point and which ones aren’t?First of all, in a lot of cases, people went to court and the courts have reversed those earlier decisions. So the first thing that happened is, courts said, “No, no, no, you can’t do it this way. You have to bring them back.” The second thing that happened is that Cabinet officers started to get confirmed by the Senate. And remember that a lot of the most spectacular DOGE stuff was happening in February. In February, these Cabinet secretaries were preparing for their Senate hearings. They weren’t on the job. Now that their Cabinet secretary’s home, what’s happening is they’re looking at these cuts and they’re saying, “No, no, no! We can’t live with these cuts because we have a mission to do.”As the government tries to hire back the people they fired, they’re going to have a tough time, and they’re going to have a tough time for two reasons. First of all, they treated them like dirt, and they’ve said a lot of insulting things. Second, most of the people who work for the federal government are highly skilled. They’re not paper pushers. We have computers to push our paper, right? They’re scientists. They’re engineers. They’re people with high skills, and guess what? They can get jobs outside the government. So there’s going to be real lasting damage to the government from the way they did this. And it’s analogous to the lasting damage that they’re causing at universities, where we now have top scientists who used to invent great cures for cancer and things like that, deciding to go find jobs in Europe because this culture has gotten so bad.What happens to this agency now? Who’s in charge of it?Well, what they’ve done is DOGE employees have been embedded in each of the organizations in the government, okay? And they basically — and the president himself has said this — they basically report to the Cabinet secretaries. So if you are in the Transportation Department, you have to make sure that Sean Duffy, who’s the secretary of transportation, agrees with you on what you want to do. And Sean Duffy has already had a fight during a Cabinet meeting with Elon Musk. You know that he has not been thrilled with the advice he’s gotten from DOGE. So from now on, DOGE is going to have to work hand in hand with Donald Trump’s appointed leaders.And just to bring this around to what we’re here talking about now, they’re in this huge fight over wasteful spending with the so-called big, beautiful bill. Does this just look like the government as usual, ultimately?It’s actually worse than normal. Because the deficit impacts are bigger than normal. It’s adding more to the deficit than previous bills have done. And the second reason it’s worse than normal is that everybody is still living in a fantasy world. And the fantasy world says that somehow we can deal with our deficits by cutting waste, fraud, and abuse. That is pure nonsense. Let me say it: pure nonsense.Where does most of the government money go? Does it go to some bureaucrats sitting on Pennsylvania Avenue? It goes to us. It goes to your grandmother and her Social Security and her Medicare. It goes to veterans in veterans benefits. It goes to Americans. That’s why it’s so hard to cut it. It’s so hard to cut it because it’s us. And people are living on it. Now, there’s a whole other topic that nobody talks about, and it’s called entitlement reform, right? Could we reform Social Security? Could we make the retirement age go from 67 to 68? That would save a lot of money. Could we change the cost of living? Nobody, nobody, nobody is talking about that. And that’s because we are in this crazy, polarized environment where we can no longer have serious conversations about serious issues. See More:
