Measuring the match degree of two or more blocks or pixels in a file carving technique is a very important key point. A lot of studies on the matching of panoramic images and continuous images have been performed. In addition, since the general image matching includes a region of overlap, it is possible to find the position of matching only by matching of features. In the beginning of this study, block matching was measured based on the same scale as MAE of neighboring pixels of the block. In the proposed method, the set of image fragments that can be morphologically paired with the image segment A is called Bi, and the prediction pixels (Ppred_A) are generated from the adjacent pixels of A and Bi by using a linear interpolation method. On the contrary, the prediction pixels Ppred_Bi are generated from neighboring pixels of Bi in the same manner. The prediction pixels obtained through this process can show a higher degree of matching than the primary block matching such as MAE by measuring the similarity of the relative pieces of the image fragment pair to the adjacent pixels.
