Abstract

"This article introduces a new image coding scheme based on the discrete cosine transform (DCT) applied to blocks of image pixels and on the run-length encoding of the binary digits of the DCT coefficients, bitplane by bit-plane. The main advantages of this new algorithm are: simplicity of implementation, efficiency superior to JPEG’s, in peak-signal-tonoise ratio (PSNR) versus bit rate, fully embedded output sequence, and all the advantages that result from the use of the DCT as the coding transform, as, for example, the possibility to be used as part of a video coder with block motion compensation, such as MPEG."
