A Fast Reassembly Methodology for Polygon Fragment

A new general methodology is introduced for computer-aided reassembly of the polygon image fragments. Since polygon image fragment has a characteristic that it has obvious corners, this methodology takes advantage of such characteristic, and detects the corners by Hough transform and fuzzy reasoning. Meanwhile, it computes the length of each side, compares the side length, finds out the sides with equal length in different fragments, and then computes the gray correlation of equal sides to determine the most optimal matching location for reassembly. Experimental results show that the reassembly methodology for polygon fragment based on corner alignment and gray correlation is effective and fast.
