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

●●SolidWizardryBig BrainNiche Gem

Golden ratio color math beats JPEG by 5.9% while keeping full 4:4:4 chroma.

Strengths
  • •Phi-derived Golden Color Transform replaces standard YCbCr with mathematically elegant constants.
  • •Turing morphogenesis saliency field enables zero-bit perceptual quantization modulation.
  • •Variable-size LOT (8/16/32) adapts block sizes to content instead of fixed 8x8 DCT.
Weaknesses
  • •Competing against AVIF, WebP, JPEG XL with massive institutional backing and hardware decode.
  • •Experimental codec with no browser support or hardware acceleration roadmap visible.
