| Abstract(in English) | JPEG2000 compression standard considers a block of wavelet coefficients, called codeblock, as the smallest coding unit that being independently entropy-coded. In this paper, we propose a codeblock-based concealment technique to mitigate missing codeblock, which occurs due to packet loss during transmission of JPEG2000 images over lossy packet networks. The proposed method utilizes multiple image representations and tiling-based JPEG2000 coding. Our technique directly substitutes the affected codeblock with a copy of the nearly accurate data obtained from the available image representations. Thus, it does not require an iterative processing, which is time consuming, to predict the lost data. Moreover, it is applicable for a large codeblock size and can be implemented either in wavelet or codestream domain. Simulation results confirm the effectiveness of the proposed method. |
