Описание тега hough-transform
The Hough transform is a technique used to isolate features of a particular shape within an image. It is most commonly used for the detection of regular curves such as lines, circles, ellipses, and so on.
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 space, from which object candidates are obtained as local maxima in a so-called accumulator space that is explicitly constructed by the algorithm for computing the Hough transform.
