Recovery method of vertical and horizontal cutting fragmented files

LIU Jun-wei;HAN Bang-he;School of Mathematics and Statistics,Xi'an Electronic and Science University;  
In order to realize quick recovery for regular shredded paper with text,a feature matching algorithm based on the edge pixels of the broken pieces was proposed.Firstly,two-dimensional gray vectors were constructed through the analysis of the edge pixel points of the shredded paper images.Then,by introducing the similarity index of the pixel gray value,regular broken piece image based twodimensional matching vectors for the gray values of edge pixel points were constructed.Additionally,a mathematical model for two-dimensional gray matching was built.Constraints on lines were introduced during the transversal matching for broken piece images to reduce longitudinal errors.Meanwhile,longitudinal matching was optimized to achieve a quick match for regular shredded paper with text.Simulation shows that,only 21(and 34)artificial adjustments were required to recover a Chinese(English)paperwork,composed of up to 209pieces,during the matching process.
