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 … See more 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 … See more In automated analysis of digital images, a subproblem often arises of detecting simple shapes, such as straight lines, circles or ellipses. … See more Example 1 Consider three data points, shown here as black dots. • For each data point, a number of lines are plotted going … See more 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 noise. This means that the bin must not be too … See more The linear Hough transform algorithm estimates the two parameters that define a straight line. The transform space has two dimensions, and every point in the transform space is … See more 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 … See more • Generalised Hough transform • Randomized Hough transform • Radon transform • Fourier transform See more WebHough-Line-Detection.

WebApr 13, 2024 · The Hough circle detection results were improved using the Vector Quantization algorithm . Regarding visual inspections of roundness, the traditional method for roundness inspection [ 27 , 28 , 29 ] was to use a probe tester, and the roundness would be determined by connecting the probe and the measured object.
