AUREA beats JPEG by compressing images using variable-size Lapped Orthogonal Transform (8/16/32), a zero-bit Turing morphogenesis saliency field, AC-domain Chroma-from-Luma prediction, and rANS entropy coding with Exp-Golomb.

AI Analysis
●●●BangerWizardryBig BrainDark Horse
Beats JPEG with zero-bit saliency fields and full 4:4:4 chroma — rare codec craft in Rust.
Strengths
- •Golden Color Transform derives weights from phi instead of standard BT.601 coefficients
- •Variable block sizes (8/16/32) adapt to content without blocking artifacts
- •Ships with CLI, native GUI viewer, and Windows shell extension for thumbnails
Weaknesses
- •No hardware acceleration or SIMD optimizations mentioned for real-world encoding speed
- •Competing against established formats like AVIF and JPEG XL with industry backing
