This slide illustrates that we initially divided the original image into 4x4 blocks. In each block, we select the pixel P33 as the reference pixel, and by replacing it with P22, P24, P42, and P44, we obtain the prediction matrix of the proposed method presented in this paper. Finally, the difference of the original image is taken from the prediction matrix, which leads to the prediction error of the original image.<br>The important point is that according to the characteristics of the prediction function in the method of this paper, in each block of the image, 0.75 of each block finds the ability
