الملخص الانجليزي
Imperfect transmission of block-coded images often causes lost blocks. These blocks may contain very important information of image. In this paper, an efficient method of error concealment scheme is proposed for restoring lost blocks and lines in medical images that are transmitted over error prone network such as the internet and wireless networks. It adopted the idea of data hiding that can be implemented in the DCT domain. The algorithm determines the most important information in each block of original image and rotated one by 900 clockwise and embeds this information into another block that is not adjacent to it, since adjacent blocks have high probability to be lost at the same time. Simulation results show that the visual quality and the PSNR evaluation of a reconstructed image are significantly improved using the proposed scheme with respect to other techniques.
