In this paper, an approach of recovery of paper scraps was proposed. First of all, adjacent bits of paper text line feature were selected, and each piece of paper was used as a node of the graph. It established a grid graph model based on the line feature of text, and narrowed the set of matching scraps of paper by considering both sides of pieces line the matching. Function values of both positive and negative similarity were added as similarity of scraps of paper, when the similarity function value reached minimum. It shows the difference of gray value of two scraps of paper writing disconnection can reach the minimum. Finally, the simulated annealing mechanism was introduced to optimize the matching process of the set of matching pieces of paper. The results showed that the algorithm can solve the problem of more complex scraps of splicing. [ABSTRACT FROM AUTHOR]

In this paper, a design method of CPU was proposed, the instruction set of the CPU contained 15 items of MIPS instruction set, and the basic method of five step pipeline CPU design was used. Analyses were conducted on the logic structure of the pipeline CPU and the processing of the instruction. This paper also gave design and realization of stage IF, stage ID, stage EX, stage MEM and stage WB. About the pipeline-related problems, the paper adopted Bubble and Forwarding technologies to eliminate it. The tests on the FPGA platform show that the scheme meets the design requirements.

In this paper, an approach of recovery of paper scraps was proposed. First of all, the number of word boundary continuous points was used as the character feature, Then gray feature of the boundary text was extracted by using the continuous eight connection method. The continuous point number feature matrix based on the gray feature is obtained through the feature extraction. Finally, the ordering of the fragments is sorted by position, computer programs are developed by C language and according to this algorithm. They are applied in a stitching experiment for pieces of scrapped paper, the results show that this algorithm meets the design requirements. [ABSTRACT FROM AUTHOR]
