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 ...

This paper presents a method that proposes the composition of the Map-Reduce algorithm and the Hough Transform method to research particular features of shape in the Big Data of images. We introduce the first formal translation of the Hough Transform method into the Map-Reduce pattern. The Hough transform is applied to one image or to several images in parallel. The context of the application o...

This paper addresses the problem of detecting mirror symportion to be analyzed needs to be segmented and to inmetries of 3D shapes. Unlike previous methods, which involve clude the overall 2D shape. Moment analysis cannot thereoverall 3D shape data, our method uses a range image obtained fore be applied to locally symmetric shapes or incomplete from one viewpoint. Also, the proposed method can ...

We present a method to automatically correct the radial distortion caused by wide-angle lenses using the distorted lines generated by the projection of 3D straight lines onto the image. Lens distortion is estimated by the division model using one parameter, which allows to state the problem into the Hough transform scheme by adding a distortion parameter to better extract straight lines from th...

This paper proposes a novel algorithm called the sparse Hough transform, which is shown to have better performances than the standard Hough transform for sparse input data collected from a laser on a mobile robot. In the context of laser sensing and perception for autonomous ground robots, this paper studies performances of the sparse Hough transform and compares it with other segmentation and ...

Kanade [1] proposed a heuristic for interpreting shape from contour. To apply his heuristic, skewed symmetries have to be found. In this paper, an algorithm for finding skewed symmetries in a planar point set is proposed. The method requires a simple rotation and midpoint finding, followed by a Hough transform. A variant of the Hough transform is reported. It is based on interpreting it as a ro...

This paper presents a feature-based approach to piecewise planar modeling of architectural scenes from an oriented image sequence. An improved line detection algorithm is presented, which uses vanishing points to detect lines in the images and reconstruct them in 3D. Subsequently an extension of the 3D Hough transform is presented which allows efficient and robust detection of planes in a set o...

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 ...

Hough transform based methods for object detection work by allowing image features to vote for the location of the object. While this representation allows for parts observed in different training instances to support a single object hypothesis, it also produces false positives by accumulating votes that are consistent in location but inconsistent in other properties like pose, color, shape or ...
