An Efficient Two-Pass Parallel Binary Image Thinning Algorithm
A. Jagna, V. Kamakshiprasad · SSRN Electronic Journal · 2010
This paper proposes an efficient parallel thinning algorithm for binary images. The proposed thinning algorithm adopts a two iteration approach, wherein four conditions are tested at each iteration by considering a sub-image of 3 x 3 size at a time. The algorithm preserves the connectivity of the input image. The experimental result shows better performance in terms of thinning and excessive erosion.
