摘要

基于图像梯度的边缘检测器的边缘评估问题已经得到了广泛的研究,并且存在一系列适用于这类边缘检测器的边缘评估技术。虽然离散二阶导数算子经常构成边缘检测方法的基础,其中使用过零来定位边缘像素,但很少有人关注直接适用于过零方法的边缘评估技术的发展。我们提出了一种新的评估技术,对由这种离散二阶导数算子定位的边缘进行角取向和位移误差的边缘灵敏度分析。该技术将有限元插值应用于二阶导数算子的输出值。因此,该方法可以直接求出由二阶导数算子定位的边,而不需要使用补充的一阶导数算子进行梯度逼近。

An empirical performance evaluation technique for discrete second derivative edge detectors
The problem of edge evaluation in relation to image gradient-based edge detectors has been widely studied, and there exist a range of edge evaluation techniques that are appropriate to such edge detectors. Although discrete second derivative operators often form the basis of edge detection methods, whereby zero-crossings are used to locate edge pixels, rather less attention has been paid to the development of edge evaluation techniques that are directly appropriate to zero-crossing methods. We propose a new evaluation technique that performs edge sensitivity analysis with respect to angular orientation and displacement errors for edges located by such discrete second derivative operators. The technique applies a finite element interpolation to the output values of the second derivative operator. Hence the method is used to directly evaluate edges located by a second derivative operator without the need to use a supplementary first derivative operator for gradient approximation.
