Ellipse Detection Using Randomized Hough Transform

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 … 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. In many cases an edge detector can … See more 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. 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 account that the local gradient of the image intensity will necessarily be … See more • Generalised Hough transform • Randomized Hough transform • Radon transform • Fourier transform See more WebThe Hough transform (pronounced /ˈhʌf/, rhymes with tough) is a feature extraction technique used in image analysis, computer vision, and digital image processing.
