Could you build this?
No Inventing and implementing a novel spatial domain variable block size luma-dependent chroma compression algorithm requires specialized research and deep signal/image processing mathematics.
What it would actually take: Development requires implementing custom color space transformations, variable block size quadtree/spatial partitioning, and luma-to-chroma correlation models in C/C++ or Rust with SIMD optimizations. The core hurdle is formulating mathematically sound lossy/lossless compression algorithms that balance rate-distortion performance against computational complexity. This demands specialized domain knowledge in information theory, video/image codecs, and perceptual image metrics.
Discussion
13 comments analyzed.
Competitors mentioned: AV1 codec (CfL chroma prediction), JPEG XL, HEVC/H.266, AV2 codec, LLIC codec
Concerns raised: State-of-the-art too complex for individual contributors to improve upon, High-entropy edge geometry data causes redundant coding overhead, Color bleeding artifacts in chroma prediction, Difficult to demonstrate novelty without integration into reference encoders
Feature requests: Shade-detection algorithm to code chroma separately per edge side, Low-resolution 2D slope representation with recursive compression, Larger quadtree leaf nodes to reduce data rate
