Method for edge detection
A computer system executes a method that detects an edge of an object with a Canny operator. The method calculates a gradient strength of pixels of the image and applies non-maximum suppression to the image to avoid spurious responses to edge detection. The image is divided into multiple partitions based on a brightness distribution of the pixels in the image and a set of dynamic threshold values. Multiple images for the partitions are superimposed to detect an edge of the object.
