Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Google's decision to deprecate JPEG-XL emphasizes the need for browser choice and free formats
I believe JXL's reference implementation isn't even to version 1 yet. 0.8.1 appears to be the latest. I could see them revisiting this once the reference implementation is considered complete.

Very large (DICOM) microscopy images region and resolution transcoding tiling and resolutions
I asked for this a while ago, not sure how things have progressed since then.

H.264 is magic: a technical walkthrough
That license doesn't say anything about patents. This one does: https://gitlab.com/wg1/jpeg-xl/-/blob/main/PATENTS and only says that patents owned by Google are covered. So it may be that other companies patent the technology. The information in the repository is not enough to decide whether JPEG XL is safe to use.

I am a co-creator of JPEG XL (.jxl), a new image format. AMA!
The GIMP plugin is a great thing. But it still can't open/save images with special chars in their filenames. French, German and many other languages are affected. Could this be fixed soon? https://gitlab.com/wg1/jpeg-xl/-/issues/184

Here's my googledrive of every current raw scan of my vintage 35mm slide collection of world travel and random families taken from estate sales around the world. Originally scanned 4800-6400dpi as .TIFFs but these are .jpegs. Feel free to comment your insight or download the whole thing. 2000+
https://gitlab.com/wg1/jpeg-xl/-/blob/main/doc/developing_in_windows.md It's not as straight-forward to build as it is on Linux. I'm not sure if there are official binaries somewhere, sorry.
- Improvements to the ubiquitous JPEG image format used across the internet will bring global bandwidth savings of 30 per cent, say the creators of the new technology, who have made it royalty-free.
- Is it possible to convert jxl directly to jxl?

JPEG XL website and conformance testcases published on GitHub
I'm guessing the reference implementation with complete git history is soon to follow? https://gitlab.com/wg1/jpeg-xl

JPEG XL support has been added to Firefox Nightly! (90.0a1 (2021-05-09)
The file format was 'frozen' last December: https://gitlab.com/wg1/jpeg-xl/-/tags/v0.2 Which is why FF can start implementing its usage.

Motion detection from video compression
look for libraries to extract motion vector from video streams. e.g. https://github.com/vadimkantorov/mpegflow or https://github.com/jishnujayakumar/MV-Tractus
What are some alternatives?
sharp - High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. Uses the libvips library.
mpegflow - A tool for easy extraction of motion vectors stored in video files
jxl-winthumb - A JPEG XL (*.jxl) thumbnail handler for Windows File Explorer.
mv-extractor - Extract frames and motion vectors from H.264 and MPEG-4 encoded video.
highway - Performance-portable, length-agnostic SIMD with runtime dispatch
Computer-Vision-Video-Lectures - A curated list of free, high-quality, university-level courses with video lectures related to the field of Computer Vision.
