Abstract:
Novel wavelet transform based schemes for coding still images and image sequences are presented. The still image codec uses a new efficient adaptive bit-plane run-length coding of the wavelet transform coefficients of images. The main merit of this coding scheme is its simplicity requiring no training or storage of codebooks and it outperforms the JPEG at low bit-rate. For image sequence coding, a very low bit-rate sub-band motion estimation/compensation video codec designed for colour video conferencing applications is presented. A full system with buffer feedback control is designed. Simulation results of transmitting colour image sequences at 9.6 to 19.2 kbit/s are given
