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.
