摘要

利用伪光谱勒让德方法研制了一种梯度检测器。该检测器在本次通信中被提出用于检测离散图像中的边缘。该探测器可应用于水平和垂直方向。它是一种可分离检测器,其平滑正交部分类似于一维陷波滤波器。该检测器的离散Canny准则值与其他已知的基本导数滤波器的准则值相似。给出了该检测器的应用实例,并通过与索贝尔滤波器的比较结果验证了该检测器的适用性和有效性。版权所有©2007 John Wiley & Sons, Ltd

On the applicability of the pseudospectral Legendre method for edge detection
The pseudospectral Legendre method is utilized to develop a gradient detector. This detector is proposed in this communication for the detection of edges in discrete images. The detector can be applied in both the horizontal and vertical directions. It is a separable detector where the smoothing orthogonal part resembles a one-dimensional notch filter. Discrete Canny's criteria values of the detector are similar to those of other known basic derivative filters. An example is given in which this detector is utilized and its applicability and validity are supported using comparison results from the use of the Sobel filter.
