Invert-and-project (IVP): A Lossless Compression Method of Multi-scale JPEG Images via DCT Coefficients Prediction
Haohan Li, Zhaoyi Sun, Jie Sun · 2023
JPEG is a widely used format for images. Most JPEG variants are based upon a block-based DCT transformation followed by quantization and entropy coding. Redundancy at row/column level is explored in [1]. Brunsli [2] and Lepton [3], lossless JPEG repacking libraries, explore redundancy at block level.
