Method and apparatus for automatic characteristic classification of lost block in picture processing system

The present invention aims as relates to the lost block characteristic judging method and apparatus for automatic image processing system in particular, to automatically determine the characteristics of a block lost during transmission so as to provide video information for recovery of the lost block. In the video processing method of the present invention for this purpose is a multilateral video conference system, when viewed video blocks loss of calculating a sum total of the time difference values ​​between pixels adjacent to the current frame and a previous frame (S102, S103) and , the sum of the step of calculating the sum total of the dispersion values ​​for the motion vectors of the neighboring blocks (S104, S105) and the sum of the inter-calculation pixel time differential value and the motion vector variance value of the lost block when viewed video block loss comparing with a preset threshold value with reference to the step (S106, S107) and the characteristic of the determined lost block to determine the characteristics of the lost block will be characterized by configured to perform the step of: recovering the lost block.
