Probabilistic hough transform
Webb11 jan. 2024 · 概率霍夫变换（Progressive Probabilistic Hough Transform） 的原理很简单，如下所述： 1.随机获取边缘图像上的前景点，映射到极坐标系画曲线； 2.当极坐标系里面有交点达到最小投票数，将该点对应x-y坐标系的直线L找出来； 3.搜索边缘图像上前景点，在直线L上的点（且点与点之间距离小于maxLineGap的）连成线段，然后这些点全部 … The Hough transform is a feature extraction technique used in image analysis, computer vision, and digital image processing. The purpose of the technique is to find imperfect instances of objects within a certain class of shapes by a voting procedure. This voting procedure is carried out in a parameter … Visa mer It was initially invented for machine analysis of bubble chamber photographs (Hough, 1959). The Hough transform was patented as U.S. Patent 3,069,654 in 1962 and assigned to the U.S. Atomic … Visa mer In automated analysis of digital images, a subproblem often arises of detecting simple shapes, such as straight lines, circles or ellipses. In many cases an edge detector can … Visa mer Using the gradient direction to reduce the number of votes An improvement suggested by O'Gorman and Clowes can be used to detect lines if one takes into account that the local gradient of the image intensity will necessarily be … Visa mer • Generalised Hough transform • Randomized Hough transform • Radon transform • Fourier transform Visa mer The linear Hough transform algorithm estimates the two parameters that define a straight line. The transform space has two dimensions, and … Visa mer Example 1 Consider three data points, shown here as black dots. • For each data point, a number of lines are plotted going through it, all at different angles. These are shown here in different colours. Visa mer The Hough transform is only efficient if a high number of votes fall in the right bin, so that the bin can be easily detected amid the background … Visa mer
