I have used sobel to get the gradient of an image in X and Y direction:
cv::Sobel( Min1, grad_x, Min1.depth(), 1, 0, 3);
cv::Sobel( Min1, grad_y, Min1.depth(), 0, 1, 3);
now I have the gradient of the Min1 in X direction stored in Mat grade_x and in Y direction stored in Mat grade_y.
How do I calculate the magnitude of grad_x and grad_y? Is there any function in Opencv to get the norm of a matrix?
Thanks in advance...
