voronoi_map::greyscale_thinning

void greyscale_thinning(const cv::Mat &src, cv::Mat &dst)

Function for finding the ridge of a distance graph.

Definition: thinning.cpp:109

voronoi_map::getMaximumNeighbour

Index getMaximumNeighbour(int i, int j, const cv::Mat &src, cv::Mat &dst)

function for finding the maximum Neighbour ignoring the last detected pixels

Definition: thinning.cpp:463

voronoi_map::sceletonize_iteration

void sceletonize_iteration(cv::Mat &img, int iter)

Perform one thinning iteration.(Normally you wouldn't call this function directly from your code)

Definition: thinning.cpp:7

voronoi_map::sceletonize

void sceletonize(const cv::Mat &src, cv::Mat &dst)

Function for thinning the given binary image (Paper Zhang-Suen Thinning)
