General hough transform software
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. See more • OpenCV implementation of generalized Hough transform • Tutorial and implementation of generalized Hough transforms See more The implementation uses the following equations: $${\displaystyle x=x_{c}+x'\ \ or\ \ x_{c}=x-x'}$$ $${\displaystyle y=y_{c}+y'\ \ or\ \ y_{c}=y-y'}$$ See more Ballard suggested using orientation information of the edge decreasing the cost of the computation.
