A Comparative Analysis of Image Error Concealment Technique

These Image Compression is the solution associated with transmission and storage of large amount of information for digital Image. Image Compression is the method of reducing the image size without corrupting the excellence of the image. And the interest in data hiding has raised with the recent activity in digital copyright security method. To protect the ownership of a digital image is to secretly embed data in the content of the image identifying the owner. In this paper, we proposed an error concealment scheme for protection of compressed image using M-ary quantization index modulation (QIM) with different block loss. The results show that the proposed error concealment scheme presents a stronger error correcting capability and superior visual quality.
