Encoding method of dinamik image stationary background in infocommunication system

Abstract

In order to improve the performance of communication systems is necessary to improve the compression tech­nology of dynamic images. Therefore justified the basic principles of a compression method of dynamic images of stationary background in information and communication systems on the basis of the formation of differential rep­resented by the frame. In order to identify the dynamic component of the threshold set out the terms of use fil­tration differential represented the frame. The technology of splitting differentially represented on the frame com­ponents: the dynamic component, a binary mask station­ary background and an array of characters. The technolo­gy of processing dynamic component, conducted on the basis of a one-dimensional position-encoding with adap­tive selection of the base. The basic steps of the method of processing the binary mask differentially represented by the frame, carried out on the basis of coding capacity of the two lengths of the binary alphabet series. Con­structed a matrix decoding technology signs, implemented on the basis of coding capacity alphabet with the structur­al similarity with the matrix of the binary mask. It is shown that the developed coding methods provide the potential for further reduction in volume and increasing die compression of dynamic images stationary back­ground, which generally leads to a reduction of processing time in information and communication systems.
