Motion picture wavelet coding is investigated. Wavelet coding[5,6,7] is expected to be a next generation transform coding, because it can reduce blocking effect and mosquito noise which are the major source of image quality degradation in conventional transform coding methods. Entropy coding of wavelet coefficients is first discussed, then blockless motion compensated adaptive inter/intra-frame prediction method is proposed for motion picture wavelet coding. Coding efficiency is evaluated by simulation. The proposed techniques improve subjective quality of decoded pictures.
