| Abstract | ||
| In this paper, we present a new proposed error concealment algorithm to improve the image quality degraded during its transmission over wireless channel. Different error concealment strategies are applied to different locations of blocks in order to achieve better visual quality. The proposed algorithm conceal the lost block using Framelet Transform (FT), this is achieved by finding the average of framelet subbands in neighbors of the lost block. Finally, the results of this algorithm compared with the results of MultiWavelet Averaging (MWA) algorithm in terms of signal to noise ratio (SNR) and human vision. | ||
