Abstract	Generally, transmission of raw image requires very high bit rates. To reduced bit rate, compression of raw image using block base coding is necessary. Further these blocks are transmitted packet by packet on transmission line but it may happen that some packets may be loss during transmission. Due to loss of packets, receiver will produced corrupted image with missing blocks, which will reduce image quality. To recover missing blocks and improve image quality, error concealment technique been used. This paper shows the performance analysis of Error Concealment (EC) technique for different lost block size (4×4, 8×8, and 16×16). Experimental results demonstrate that error concealment technique provides better improvements in PSNR (dB) and SSIM for small lost block size, which clearly indicates that EC method able to recover small lost block size more efficiently compared to large lost block size.
