canny edge detection for find edge in image processing.is the best edge detector for object segmentation

canny edge detector is the best edge detection in the image processing field.in the first guassian blur in the image and then use sobel filter to get magnitude image

Object detection (or rather, recognition) is one of the fundamental problems in computer vision and a lot of techniques have come up to solve it. Invariably all of them employ machine learning, because the computer has to first learn that a partic
