| Abstract: | In this paper,a new theory and a method for predictive processing based on two valued image compressing are proposed and an algorithm based on mathematics for improving the efficiency of WBS coding and block coding of binary image is presented.The basic principle is to eliminate the black straight line sectors(vertical or horizontal) by preprocessing them before encoding.The compression ratio is then increased. |

| Keywords: | two valued image coding predictive processing compression algorithm |
