Journey to JPEG XL: open-source experiments shaped the future of image coding
Building the Next Generation Image Standard The internet runs on images. Since the early days of the web, there has been a relentless tension between visual fidelity and bandwidth. For decades, the industry relied on the venerable JPEG standard for images loading fast.
Places in the Wild: A Large, High-Resolution RAW Photograph Dataset for Ecologically Valid Vision Research
arXiv:2606.02481v1 Announce Type: new Abstract: Large image datasets have accelerated progress in cognitive neuroscience and computer vision. However, most datasets are low-resolution, internet-sourced JPEGs with unknown capture conditions and limited spatial context. Places in the Wild is a dataset of 67,574 high-resolution photographs collected in situ across 810 physical locations spanning 260 basic-level scene categories, including indoor, urban, and natural environments.
SEAOTTER: Sensor Embedded Autoencoding with One-Time Transcode for Efficient Reconstruction
arXiv:2606.03940v1 Announce Type: cross Abstract: In robotics systems, vast amounts of visual data are easily captured at high resolution using low-cost, low-power hardware. Yet, limited bandwidth and on-device compute resources prevent full utilization when transmitted via conventional codecs like JPEG/MPEG. Newer codecs, like AV1/AVIF, improve the rate-distortion trade-off, but demand far more resources for encoding, impractical without custom ASICs.
ESP32-S31
Comprehensive Connectivity ESP32-S31 integrates both wireless and wired connectivity for versatile networking. It supports 2.4 GHz Wi-Fi 6 (802.11ax) for enhanced transmission efficiency and reduced power consumption, making it ideal for battery-powered and always-connected devices. IEEE 802.15.4 enables Thread and Zigbee protocols, and Bluetooth® 5.4 (LE) supports LE Audio for high-quality, low-power audio streaming, Direction Finding, and Bluetooth Mesh 1.1 for scalable many-to-many device...
Spatial Artifact Coherence Determines Codec Robustness in Patch-Based rPPG
arXiv:2606.04198v1 Announce Type: new Abstract: Remote photoplethysmography (rPPG) achieves low heart-rate error on uncompressed benchmarks yet is deployed over compressed video channels in telehealth, neonatal ICU, and driver fatigue applications. No prior work identifies the physical quantity determining when spatial decomposition outperforms global-projection methods under codec compression. We propose Spatial Artifact Coherence (SAC), defined as the ratio of off-diagonal to diagonal...
PlayStation Architecture
Supporting imagery A quick introduction Sony knew that 3D hardware could get very messy to develop for. Thus, their debuting console will keep its design simple and practical… Although this may come at a cost!

Here's what you should and shouldn't plug into a TV USB port
Here's what you should and shouldn't plug into a TV USB port These ports are often forgotten, but can still be useful. Modern smart TVs tend to have some USB ports that are easy to forget about, especially with those HDMIs gobbling up all of the oxygen. Most new sets feature at least one of these ports, typically located on the side or the back.
