Image Stitching Method of Bone Stick Fragment Based on Similarity Freeman Code Matching

A large number of bone stick fragments were unearthed at the Weiyang Palace, and manual stitching method is inefficient time-consuming, therefore Image Stitching Method Bone Stick Fragment Based on Similarity Freeman code Matching proposed by this paper to improve efficiency. The used represent contour true color RGB image fragments, direction change dense feature fragment fracture fused with difference locate boundary. At same time, integer basic operation replace complex calculus calculation efficiency algorithm; longest common subsequence algorithm perform local similarity rough matching fracture, then angle distance error threshold set according prior knowledge reduce error; Finally, results, complete binary drawn. Compared other algorithms, Cosine accuracy stitched improved 21.68%, which can be accurate 97.80%; Editing 14.29%, 91.87%;the Peak signal-to-noise ratio 83%, 31.13%;the Structural 29%, 0.87; Figure merit 39%, 0.85. experiment results show that in effectively assist work cultural relics.
