A probabilistic Hough transform

Pattern Recognition, 1991
Abstract The Hough Transform for straight line detection is considered. It is shown that if just a small subset of the edge points in the image, selected at random, is used as input for the Hough Transform, the performance is often only slightly impaired, thus the execution time can be considerably shortened.

A combinatorial Hough transform

Pattern Recognition Letters, 1990
Abstract A new algorithm for computing the Hough transform is presented. It calculates the parameters associated with all possible combinations of two-point line segments among the feature points in the image, rather than calculating all possible values of one of the parameters searched.

Fast generalized Hough transform

Pattern Recognition Letters, 1990
Abstract A fast algorithm for the generalized Hough transform (GHT) based on the use of a hierarchical processing scheme and the inverse generalized Hough operation is proposed. By reducing the size of the image portion which need be processed in the proposed fast GHT, not only the computation time but also the number of processing elements for ...

Hierarchical generalized Hough transforms and line-segment based generalized Hough transforms

Pattern Recognition, 1982
Abstract Generalized Hough transforms are fast point pattern matching algorithms which have applications in image processing. Two extensions to generalized Hough transforms are described. The first allows for matching hierarchically organized point patterns. An example concerning image registration using hierarchical point patterns is described.

Probabilistic Convergent Hough Transform

2008 International Conference on Information and Automation, 2008
To reduce the computational complexity, a novel method of standard Hough transform (SHT), named probabilistic convergent Hough transform (PCHT), is proposed in this paper. PCHT avoids unnecessary cost of SHT in computation by intermittently detecting several points of a line through fast convergence and in memory by using a one-dimensional accumulator.

Antialiasing the Hough transform

CVGIP: Graphical Models and Image Processing, 1991
Abstract The discretization of the Hough transform parameter plane is considered. It is shown that the popular accumulator method implies sampling of a nonbandlimited signal. The resultant aliasing accounts for several familiar difficulties in the algorithm. Bandlimiting the parameter plane would allow Nyquist sampling, thus aliasing could be avoided.

The Hough Transform

2019
The Hough Transform is widely used to detect parametrically described curves in an image that can contain noise or partial occlusion. It is shown how a two dimensional linear Hough Transform can be used to identify track candidates within the CMS tracker.

Fast linear Hough transform

Proceedings of IEEE International Conference on Application Specific Array Processors (ASSAP'94), 2002
The Hough transform is the choice technique for identifying straight lines through digital images, with applications to high energy physics and computer vision. Classical methods for implementing the Hough transform of a N/spl times/N binary image require to compute N/sup 3/ additions over n=log/sub 2/(N) bits integers, hence nN/sup 3/ bit operations ...
