Abstract
JPEG2000, an international standard for still image compression, has three main features: 1) high coding performance; 2) unified lossless/lossy compression; and 3) resolution and SNR scalability. Resolution scalability is especially promising given the popularity of super high definition (SHD) images like digital-cinema. Unfortunately, the resolution scalability of its current implementation is restricted to powers of two. In this paper, we introduce non-octave scalable coding with a motion compensated interframe wavelet transform. By using the proposed algorithm, images of rational scales can be decoded from a compressed code stream. Experiments on SHD digital cinema test sequences show the effectiveness of the proposed algorithm.
