A Method Of Compression Of Digital Images Using A Fixed Number Of Bits Per Block
Abstract: A method of compression of digital images using a fixed number of bits per block is described. Intra-coding is used for lossless compression of digital images. The image is partitioned into blocks with the same size. The encoder generates a fixed and predetermined number of bits for each block. The encoding process includes gamma conversion applied to the input image to generate data. Additional stages include prediction quantization DPCM entropy coding and refinement.
