Edge detection algorithms have traditionally utilized the Gaussian Linear Filter (GLF) for image smoothing. Although GLF has very good properties in removing noise and unwanted artifacts from an image, it is also known to remove many valid edges. To cope with this problem, edge preserving smoothing...

A Sobel filter is one edge detection method. It detects a gradient by performing “convolutions” on the grayscale input image. A “convolution” is a fancy name for a weighted sum of neighboring pixels. The specific weights in the sum are called a “kernel” in the jargon. Here is an...
This correspondence examines the use of nonlinear edge enhancers as prefilters for edge detectors. The filters are able to convert smooth edges to step edges and suppress noise simultaneously. Thus, false alarms due to noise are minimized and edge gradient estimates tend to be large and localized...
In this article, we have examined what edge detection/feature extraction looks like from a computer vision point of view using some predefined filters. It is worthy of note however that a CNN will not be using these predefined filters for edge detection, it will rather learn the best filters...

The performance of a Gabor odd filter-based edge detector is investigated using the measures proposed by Canny. Based on this performance analysis a design criterion for 1-D Gabor filter-based edge detector is derived. It is shown that this design criterion holds good for a 2-D Gabor filter...
aThere are many methods of edge detection that have been published mainly differ in the types of smoothing filters that are applied and the way the measures of edge strength are computed. 有在使过滤器光滑的种类被出版了主要不同是应用的边缘检测的许多方法,并且方式边缘力量措施被计算。[translate]...
摘要: The paper presents our research in image processing (filters used for edge detection, color transformation, and distortion correction) using artificial neural networks. We have developed a tool, Neuron Color, in order to carry out these experiments and improving our adaptive methods.关键词:...
