NASA's Astronomy Picture of the Day features a before-and-after comparison of the Andromeda galaxy, demonstrating how long-exposure images taken from Earth suffer from artifacts like satellite trails and cosmic ray streaks. The 'after' image was not created using Photoshop but through specialized software that removes these terrestrial imperfections to reveal the galaxy's true appearance.
Rumors say the Galaxy S27 Ultra will overhaul its camera with warmer, more natural colors and finer detail through new image-processing algorithms, plus pro-grade video features including a low-compression Advanced Professional Video codec, 4K at 120fps, 8K at 30fps, and an updated log HDR format, signaling a shift toward realism in mobile imaging and a potential benchmark for creators.
A tech rumor suggests Samsung’s Galaxy S27 Ultra will overhaul its image processing to render photos more natural with warmer tones, addressing prior oversaturation. The report also claims updates to the Log format and Advanced Professional Recording (APV) codec to improve HDR video, while 4K at 120FPS and 8K at 30FPS remain supported. No official confirmation from Samsung yet.
Warwick researchers used a novel image‑processing approach to reanalyze data from the Isaac Newton Telescope and found 25 debris tracks in geostationary orbit (about 36,000 km up), 80% of which were previously unknown. The tiny fragments could linger indefinitely in GEO due to the near‑vacuum, creating a potentially dangerous debris cloud that threatens expensive satellites and underscores the need for debris surveys before GEO launches, with the study published in the Journal of Astronautical Sciences.
AI from UC Santa Cruz has dramatically sped up James Webb data analysis and is now being applied to the Vera C. Rubin Observatory. The Neo model, a conditional GAN trained on Subaru and Hubble images, removes atmospheric blur and recovers fine details, boosting galaxy morphology measurements by about 2–10× and turning Webb-scale processing into days rather than years. When used on Rubin data, the technology aims to sharpen ground-based images so they rival space-based quality, helping maximize the science return from Rubin’s Chilean sky survey without replacing astronomers. The work is GPU-accelerated (NVIDIA) and underscores AI’s potential to accelerate discoveries across major observatories.
Modern smartphones run AI in the background to blend multiple captures and apply edits—boosting sharpness, HDR, and even beauty filters—often making photos look more polished than what was captured. While this improves images, it can distort reality and shape memories; you can disable AI features or shoot RAW if you want truly unedited photos.
The article discusses the nature of unprocessed photos, emphasizing that all images undergo some form of processing, whether in sensor signal interpretation, demosaicing, or post-capture editing. It highlights the importance of understanding how raw sensor data is transformed into final images, the role of green in luminance, and the subjective nature of 'processing' and 'fakeness' in digital photography.
Apple researchers have developed DarkDiff, an AI model integrated into the camera's image processing pipeline that significantly enhances extremely low-light photos by recovering detail from raw sensor data, outperforming previous methods, though it currently requires high computational power and is not yet available on iPhones.
Lux, creators of the Halide camera app, reviewed the iPhone 17 Pro, praising its new 4x and 8x telephoto zoom capabilities, significant upgrades to the 2x zoom, and improvements in image processing, highlighting the phone's advanced hardware stabilization and software enhancements for professional-quality photography.
Researchers at Penn State have developed a metasurface, an optical element that mimics the image processing capabilities of the human eye, allowing for instantaneous image transformation before digitalization by a camera. This innovation has the potential to significantly reduce the computing power and energy required for artificial intelligence systems to process images and identify objects, making it easier to recognize objects across different scales and orientations. The metasurface works using nanostructures to bend light and can be applied in various fields, including target tracking, surveillance, and satellite imaging.
The Event Horizon Telescope (EHT) Collaboration has released the sharpest image of the M87 black hole yet, using an additional telescope and independent data from 2018. The new image displays the chaotic nature of the black hole's accretion disk and confirms the accuracy of the image technique. The image also shows the Doppler/Einstein effects, with the brightest spot shifting to the right between the capture of two images. Scientists plan to continue advancing the science with new observations set for the first half of 2024, aiming to capture multiple images to create the first "video" of a black hole.
The upcoming OnePlus 12 is expected to finally address the long-standing stigma of underperforming cameras in OnePlus phones. With a triple camera system including a 64MP telephoto lens, improved image processing techniques, and video features such as 8K recording and AI-assisted capabilities, the OnePlus 12 aims to compete with top flagship phones from Apple, Samsung, and Google. The use of AI and the Snapdragon 8 Gen 3 chip are anticipated to enhance the camera's performance, potentially positioning the OnePlus 12 as a strong contender for the title of best camera phone.
The upcoming Samsung Galaxy S24 Ultra is rumored to feature significant camera upgrades, including improved image processing that aims to deliver more realistic results. The phone is expected to rival Google's Pixel lineup in terms of photo capture ability. Additionally, leaks suggest that the Galaxy S24 Ultra will have a titanium frame, which is said to be 56% stronger than aluminum and is rumored to look "far better" than the iPhone 15 Pro. However, storage configurations will remain unchanged, and the phone is expected to retain the same options as its predecessor, the S23 Ultra.
Researchers have developed a deep-learning method that simplifies the creation of holograms, allowing 3D images to be generated directly from 2D photos captured with standard cameras. This technique outperforms current high-end graphics processing units in speed and doesn't require expensive equipment like RGB-D cameras, making it cost-effective. The approach involves three deep neural networks that transform a 2D color image into data that can be used to display a 3D scene or object as a hologram. This breakthrough has potential applications in high-fidelity 3D displays and in-vehicle holographic systems, revolutionizing holographic technology.
Bing Image Creator, powered by DALL-E 3, allows users to generate AI-generated images for free with a Microsoft account.
