摘要:
分析了现代边缘检测器--高斯-拉普拉斯算子过零点检测边缘时,空间常数对边缘定位的影响,讨论了区别真假边缘的理论和方法,研究了边缘之间相互作用对边缘定位的影响.实验表明,同传统的边缘检测算子相比,该方法具有良好的噪声抑制特性和边缘点的精确定位.
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.
