Edge Detection of Depth Image Based on Contour Curve

WebMay 17, 2016 · Generally edge detection boils down to detect areas of the image with high gradient value. In our case we can crudely see the gradient as the derivative of the image function, therefore the magnitude of the gradient gives you an information on how much your image changes locally (in regards of neighbouring pixels/texels). WebMar 20, 2015 · If you instead use the saturation channel to extract edges, you'll end up with something like this: cv::Mat cannyS; cv::Canny (S, cannyS, 200, 100); where the contours aren't completely closed. Maybe you can combine hue and saturation within preprocessing to extract edges in the hue channel but only where saturation is high enough. orange activities
