Image Error Concealment Based on Watermarking
Imperfect transmission of block-coded images often causes lost blocks. These blocks may contain very important information of image. In this paper a new error concealment scheme is proposed for restoring lost blocks of images. It is based on the robust watermark technique to restore lost blocks in the region-of-interest (ROI) and the best-neighborhood-matching (BNM) technique to restore lost bl...
متن کاملOn JPEG2000 Error Concealment Attacks
In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealm...
متن کاملMultiple Descriptions , Error Concealment , and Re ned Descriptions for Image
{ This paper demonstrates the conservative nature of a multiple description approach to image and video coding, by showing that error con-cealment of a sub-optimally partitioned coded image stream yields comparable results under realistic conditions. Rather than use the non-orthogonal transforms of multiple description coding, which result in excess rate when both streams are received, a standa...
متن کاملA 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 sec...
متن کاملPerformance Evaluation of Spatial Domain Error Concealment for Image Recovery
Many spatial domain error concealment techniques, which are used in decoder to improve visual quality of damaged images, have been proposed in the past years. Each algorithm is based on different assumptions and has different performance under different conditions. However, there is no extensive comparative evaluation available in literature. Performance evaluation helps us to understand the st...
