TLDR
The results show that each set of coded information is transparent to any other and that each shape-indicative distribution may be located using a convolution mask peculiar to that distribution.Abstract:
A general method is presented that uses the Radon transform as a means of defining a two-dimensional transform space in which information about different, analytically defined shape primitives in an edge image space may be encoded simultaneously. Examples are given illustrating how the shape-indicative distributions within the transform space may be deduced. The results show that each set of coded information is transparent to any other and that each shape-indicative distribution may be located using a convolution mask peculiar to that distribution.read more

A survey of the Hough transform

TL;DR: This survey will provide a useful guide to quickly acquaint researchers with the main literature in this research area and it seems likely that the Hough transform will be an increasingly used technique.

X-ray imaging and analysis techniques for quantifying pore-scale structure and processes in subsurface porous medium systems
TL;DR: X-ray microtomographic imaging is a non-destructive technique for quantifying these processes in three dimensions within individual pores, and as reported here, with rapidly increasing spatial and temporal resolution.

A probabilistic Hough transform
TL;DR: 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.

TL;DR: A completely automated system which couples automatic analysis of electron backscatter diffraction diffraction patterns (EBSPs) with precise movement of the sample in the SEM is described and the Hough transform approach to correctly identify diffraction bands is quantitatively compared with the Burns algorithm.

Image processing procedures for analysis of electron back scattering patterns
TL;DR: This paper presents ways to automatically detect and localize bands in EBSPs and thereby enable fully automatic EBSP analysis using a modified Hough transform.

Use of the Hough transformation to detect lines and curves in pictures
Richard O. Duda,Peter E. Hart +1 more
TL;DR: It is pointed out that the use of angle-radius rather than slope-intercept parameters simplifies the computation further, and how the method can be used for more general curve fitting.

Generalizing the hough transform to detect arbitrary shapes
TL;DR: It is shown how the boundaries of an arbitrary non-analytic shape can be used to construct a mapping between image space and Hough transform space, which makes the generalized Houghtransform a kind of universal transform which can beused to find arbitrarily complex shapes.

Hough Transform from the Radon Transform
TL;DR: An appropriate special case of a transform developed by J. Radon in 1917 is shown to have the major properties of the Hough transform which is useful for finding line segments in digital pictures.
