Abstract
JPEG2000, an international standard for still image compression, has various features, such as high coding performance, unified lossless/lossy compression, resolution scalability and SNR scalability. Resolution scalability is an especially promising feature. Unfortunately, the current implementation of resolution scalability is restricted to powers of two. We propose non-octave scalable coding. Two types of non-octave scalable coding are implemented. One is based on a DCT filter bank and the other uses a wavelet transform. The latter model is compatible with JPEG2000, part 2. By using the proposed algorithm, images of various resolutions can be decoded from a compressed bit stream. Experimental results show the effectiveness of the proposed algorithm.
