Today we'll start talking about how to group isolated edge points into image structures. We'll come back later to talk about edge thresholding, edge relaxation, edge linking, and optimal edge determination using graph searching. All of these require some continuous path ofMorse, Bryan S...
A method of path edge extraction based on the Hough transformation was proposed with the visual navigation of imagery processing technology as foundation.First,the path image was carried on the filter pretreatment.Next,the image after process was divided by using the auto-adapted threshold value divi...
Using Unit-Linking PCNN,minimum cross-entropy rule,edge detection pre-processing and process of image dividing blocks,gray image is segmented into binary image. 利用Unit-Linking PCNN模型,结合最小交叉熵准则,边缘检测预处理,均匀分块处理,将灰度图像分割成二值图像,在二值分割图基础上实施Unit-Linking PC...

An overview of several research results in edge detection techniques over the last decade is provided with the present paper. First, the aim of detecting edges is emphasised from gathering various points of view. Main features for edge detectors to be ev
Therefore there is a need for automation of lineament mapping using optimal edge detection techniques. Efforts made in this direction include the application of Sobel and Prewitt operators or directional detectors followed by edge linking techniques (e.g. the HOUGH Transform). It is difficult to ...
