WebPVC Hough. 摘要：. This patent relates to a method and means for recognizing a complex pattern in a picture. The picture is divided into framelets, each framelet being sized so that any segment of the complex pattern therewithin is essentially a straight line. Each framelet is scanned to produce an electrical pulse for each point scanned on ... WebAbstract A variety of circle detection methods which are based on variations of the Hough Transform are investigated. The five methods considered are the standard Hough Transform, the Fast Hough Transform of Li et al. 1, a two stage Hough method, and two space saving approaches based on the method devised by Gerig and Klein 2.

This paper deals with the reduction of straight-line detection time with the standard Hough transform method. The number of processed pixels is reduced and therefore contributes to improve the processing time. In a preprocessing step, the image is divided into rectangular boxes and only boxes with a certain percentage of high ...
