WebEdge detection is one of the fundamental operations when we perform image processing. It helps us reduce the amount of data (pixels) to process and maintains the structural aspect of the image. We're going to look into two commonly used edge detection schemes - the gradient (Sobel - first order derivatives) based edge detector and the Laplacian ... Web5. You can get the x-derivative dx and y-derivative dy using Sobel operator. Then you can use the formula to calculate the magnitude and direction of the gradient. G=sqrt (dx^2+dy^2), theta=arctan (dy/dx). You can find this is just convert descartes coordinate system (x,y) to polar coordinates (rho, theta)! There is something wrong in your code ...
