A spatial loss concealment algorithm for reconstruction of the lost blocks in the I-frames of a video sequence is proposed. The algorithm is carried out in three steps. In the first step an edge directional analysis on the boundaries of the lost blocks is carried out. In the second step, the lost pixels are approximated from the available neighboring blocks of that boundary. In the third step, the derived approximations of all available boundaries are combined for final reconstruction of the lost pixels. Experimental results over an H.264/AVC codec show an improvement of about 0.5-1dB over a similar spatial loss concealment algorithm. The subjective quality of loss concealed pictures is also evaluated through SSIM measure.
