how to use the output of Sub-Pixel Edge Detection Algorithm
Hi, I am using Sub-Pixel Edge Detection algorithm Implementing according to Carsten Steger's method. The Algorithm is taken from Github :https://github.com/songyuncen/EdgesSubPix
The output is a struct as following
struct Contour
{
std::vector<cv::Point2f> points; // edge location
std::vector<float> direction; // direction of the gradient in edge point,
// starting from y axis, counter-clockwise
std::vector<float> response; // amptitude of the gradient in edge point
};
How do i use the data of direction and response parameters for drawing and what is the meaning of these parameters?
Thanks
you'll have to read the paper
just curious: what are you trying to use this for ?
This algorithm is used for edge detection of translucent surfaces. Images are taken in gray scale.
