This paper proposes a multiple description coding (MDC), considering the structure of JPEG 2000 (JP2) code streams, to improve the quality of transmitted images. The two major features of the proposed MDC are the following; (1) The unit for transmission and reconstruction is code block (CB) that is the minimum unit independently coded in JP2. (2) It improves the image quality twice in an MDC decoding. By (1), only the area corresponding to the lost CB is distorted and the rest is free from distortion. For (2), two different process for quality improvement are applied to a JP2 code stream and its decoded spatial image. With two features mentioned above, the proposed MDC is capable to improve the quality of transmitted images much more. Moreover, since JP2 encoding and decoding are separated from other processes, it is able to employ any standard JP2 codec into the proposed MDC. Simulation results show the effectiveness of the proposed MDC. |
