LL‐FMC: Low‐latency frame memory compression scheme with high reconstructed quality

Electronics Letters, Volume 59, Issue 14, July 2023., 2023
This study proposes a Huffman coding with a fixed codebook designed to considerably reduce the latency caused by arithmetic coding in lossless compression schemes. This study also proposes a novel lossy frame memory compression technique based on the Hadamard transform that does not require additional memory access using a lookup table.
