| Abstract: |
JPEG2000, an international standard for still image compression, has various features such as 1) high coding performance, 2) unified lossless/lossy compression, 3) resolution and SNR scalability. Especially, the resolution scalability is regarded as a promising feature for Super High Definition (SHD) images like digital-cinema. However, the resolution scalability is restricted only to octave one. In this paper, we introduce a non-octave resolution conversion method which is compatible with JPEG2000 part2. By using the proposed algorithm, various types of resolution images can be decoded from a compressed JPEG2000 part2 code stream. Experimental results for digital cinema test sequences show the effectiveness of the proposed algorithm. |
