Wavelet transform based adaptive bit-plane run-length coding for still images

A novel still image codec is presented that uses an efficient adaptive bit-plane run-length coding on the wavelet transform coefficients of images. The main attraction of this coding scheme is its simplicity in which no training and storage of codebooks are required. Also its high visual quality at high compression ratio outperforms the standard JPEG codec for low bitrate applications. A comparative performance between the new codec and the JPEG codec is given.
