The article introduces libwce, a minimal implementation of the entropy layer for wavelet-based image codecs, focusing on Bit-Plane Count (BPC) coding similar to JPEG XS. The library is implemented in a single 500-line Rust file with no external dependencies, providing a clean reference for understanding wavelet coefficient encoding. While technically interesting for codec developers, it's a narrow implementation rather than a breakthrough.
Background
Wavelet-based image compression is an alternative to traditional DCT-based methods like JPEG, offering better quality at low bitrates without block artifacts. Entropy coding is the final stage of compression that converts transformed coefficients into a compressed bitstream.
