Apparatus and method for lost block concealment in an image transmission system

Abstract

A method for recovering a lost block of an image processing system, which includes determining characteristics of a lost block by using a cost function with respect to the lost block, and recovering the lost block by applying an error concealment method that is best suitable for the characteristics of the lost block. Because an image is restored by applying the most suitable error concealment method according to characteristics of the lost block, error restoration performance of a receiving end is improved and the closest image of an original image can be reproduced.
