Abstract

The fast implementation of thresholding hysteresis for edge detection is presented. Hysteresis, the optional final part of edge detection algorithms, aims at finding these parts of real edges, which were not detected, because their strength is depreciated by the noise in image. Hysteresis can be effectively computing using connected components analysis from graph theory. Using algorithm presented in [2] called in this paper as UNION-FIND the computation of hysteresis can be done with referring to the gradient information only in two image passes.
