Recurrent and generalized hough transforms
WebHough Transform for Curves (Generalized Hough Transform) The H.T. can be generalized to detect any curve that can be expressed in parametric form: – Y = f(x, a 1, a 2,…a p) – Or … WebDec 19, 2010 · Does anyone have codes for the 'Generalized Hough transform'. Or knows a website that has some. I spent 2 days on Google trying to find some but, no forum and no tutorial that have found have code for the 'Generalized Hough transform'. They only have code for analytic curves (circles, ellipsis, parabolas,... ).

WebDepartment of Computer Science CSU – Department of Computer Science ... WebJan 1, 1981 · The Hough transform is a method for detecting curves by exploiting the duality between points on a curve and parameters of that curve. The initial work showed how to detect both analytic curves (1,2) and non-analytic curves, (3) but these methods were restricted to binary edge images.

Ballard in 1981, is the modification of the Hough transform using the principle of template matching. The Hough transform was initially developed to detect analytically defined shapes (e.g., line, circle, ellipse etc.). In these cases, we have knowledge of the … See more Merlin and Farber showed how to use a Hough algorithm when the desired curves could not be described analytically. It was a precursor to Ballard's algorithm that was restricted to translation and did not account for See more To generalize the Hough algorithm to non-analytic curves, Ballard defines the following parameters for a generalized shape: a={y,s,θ} … See more Advantages • It is robust to partial or slightly deformed shapes (i.e., robust to recognition under occlusion).
