WebDevernay sub-pixel correction algorithm. The edges detected by Canny are at the pixel level, and sometimes the accuracy is lower than one pixel, that is, sub-pixel edge extraction. Devernay [3] expanded on the basis of Canny algorithm: the new edge points are defined as adjacent The maximum value of the gradient modulus difference can be ... WebYou input an image. The application performs edge detection and converts detected edges to lines. A sub-pixel edge detection algorithm [1] is used in this step. The application makes lines into an one-liner line. The details of this step can be found in the source code.
