Abstract:
The influence of spatial constants on edge localization when the Gaussian-Laplace operator crosses the zero point to detect edges is analyzed by modern edge detectors, the theory and method of distinguishing true and false edges are discussed, and the influence of interaction between edges on edge localization is studied. Experiments show that compared with the traditional edge detection operator, the proposed method has good noise suppression characteristics and accurate positioning of edge points.
