Abstract

The disadvantages of the Fast Thinning Algorithm and Improved OPTA Thinning Algorithm, i.e. incomplete thinning, not smooth and burr were analyzed and studied. The serial algorithm based on 4-connectivity parallel thinning was presented which had the advantage of quick speed and complete thinning. The lookup tables method was introduced in order to improve the operation speed. The thinned thenar palm print skeleton is smooth, no burr and located in the center of the ridge. The result of experiment is perfect.
