The Lancero JPEG-LS Lossless Image Encoder for FPGAs is an efficient implementation of the best-in-class lossless image compression standard JPEG-LS (ISO/IEC 14495-1 and ITU-T Rec. T.87).
JPEG-LS performs better than JPEG-2000 in most lossless use cases but with a much lower resource count, no need for external memory. And less than one line of latency.
