Adaptive coding of monochrome and color images

Wen-Hsiung Chen, +1 more
TL;DR: An efficient adaptive encoding technique using a new implementation of the Fast Discrete Cosine Transform (FDCT) for bandwidth compression of monochrome and color images is described, demonstrating excellent performance in terms of mean square error and direct comparison of original and reconstructed images.
