用OpenCV实现的Matlab中形态学细化、提取骨架、收缩算法。测试效果与Matlab相同。(Algorithms of morphological thinning,Skeleton and Shrink,ported from Matlab to OpenCV.)

This demonstration is intended for people who know something about the theory of the discrete Fourier transform, and who would find it helpful to see some its properties demonstrated graphically, using a programming language. The demonstration shows the form of the Fourier components of a signal in 1-D and in 2-D, and shows how elementary filtering can be applied in the Fourier domain.
