What is the difference between a Line and an Edge in image detection?

Question

We have been learning about methods like Sobel and Roberts\' convolution matrices to detect edges within images, extending to the Canny method to clear them up. But now, we

Answer 1

Methods like Sobel and Roberts help you to detect edges in the image. Methods like Hough Transform help to identify if these edges are actually geometrical shapes such as lines, circles and ellipses.
