Processed each frame to isolate the area of interest and used Hough Transform technique to identify … WebFeb 10, 2024 · The Hough transform is a general technique for identifying the locations and orientations of certain types of features in a digital image. Developed by Paul Hough in 1962 and patented by IBM, the transform consists of parameterizing a description of a feature at any given location in the original image’s space.

The generalized Hough transform (GHT), introduced by Dana H. 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 … 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} where y is a reference origin for the shape, θ is its orientation, and s = (sx, sy) describes two orthogonal scale factors. An … See more Advantages • It is robust to partial or slightly deformed shapes (i.e., robust to recognition under occlusion). • It is robust to the presence of additional structures in the image. • It is tolerant to noise.
