The Hough Transform Estimator∗
This paper pursues a statistical study of the Hough transform; the celebrated computer vision algorithm used to detect the presence of lines in a noisy image. We first study asymptotic properties of the Hough transform estimator, whose objective is to find the line that “best” fits a set of planar points. In particular, we establish strong consistency, rates of convergence and characterize the ...
متن کاملThe Cascaded Hough Transform
When using the original slope-intercept parameter-isation for the Hough transform, the resulting parameter space actually corresponds to the dual space. Indeed , lines are transformed into points, and for every point there is also a corresponding line. This paper presents a way of exploiting this special property, by the introduction of the Cascaded Hough Transform, or CHT for short. This allow...
متن کاملCharacterizing the hierarchical Hough transform through a polygonal approximation algorithm
We propose to study the relationship between the hierachical Hough transform and classical algorithms for partitioning curves into segments. We show that the set of segments found by classical algorithms is a subset of the segments found by the hierarchical Hough transform. This new relationship allows to have a better understanding of the behaviour of some parameters of the hierarchical Hough ...
متن کاملImproved Curve Detection through Decomposition of the Hough Transform
This paper describes techniques to perform fast and accurate curve detection using a variant of the Hough transform. It is shown that the Hough transform can be decomposed into many small subproblems, where each sub-problem considers only curves that pass through some subset of the points. These curves correspond to a manifold in the parameter space. This property allows the eeects of localizat...
متن کاملImproving the generalized Hough transform through imperfect grouping
This paper analyses the improvements that can be gained in the generalized Hough transform method for recognizing objects through the use of imperfect perceptual grouping techniques. In particular, we consider simple grouping techniques that determine pairs of points that are likely to belong to the same object using a criterion based on connectedness in the image edge map. It is shown that suc...
