Fast Shape Retrieval Based on Differential Chain Code Descriptor and Fuzzy Contour Matching

This work converts CAD contour matching into a differential chain-code sequence problem, then uses segmented fuzzy matching and SVD verification to retrieve similar shapes quickly and robustly under noise, scale changes, and partial contour deformation.
