Image Compression Based on LDPC Codes

By Andrey Belogolovyi


This paper describes the code-based approach to the still image compression using vector quantization. Low-density parity check codes (LDPC) are considered as vector quantizers, and the procedure of LDPC decoding can be used as fast search of the quantizer. For special images the compression ratio is greater than compression ratio by JPEG algorithm with equal quality of reconstructed image
