The problem of fitt,ing straight lines to a, number of data points arises frequently in image processing and comp~it~er vision. In this paper, we consider two approaches to solve the line detection problem in range images. The first is a simple 3D approach that finds the best line among a randomly selected subset of lines each through a pair of edge points. The second approach, based on tabu se...

A morph between two straight-line planar drawings of the same graph is a continuous transformation from the first to the second drawing such that planarity is preserved at all times. Each step of the morph moves each vertex at constant speed along a straight line. Although the existence of a morph between any two drawings was established several decades ago, only recently it has been proved tha...

Building a computational model for how the visual cortex identifies objects is a problem that has attracted much attention over the years. Generally, the interest has been in creating models that are translation, rotation, and luminance invariant. In this paper, we utilize the philosophy of Hough Transform to create a model for detecting straight lines under conditions of discontinuity and nois...

Achilles tendon length has been measured using a straight-line model. However, this model is associated with a greater measurement error compared with a curved-line model. Therefore, we examined the influence of neglecting the curved path of the Achilles tendon on its length change at various ranges of motion. Ten male subjects participated in this study. First, the location of the Achilles ten...

As to aided driving by harvesting robot, there is the large amount of image data processing, meanwhile, harvesting robot requires real-time image processing and to calculate the linear parameters in a straight line detection of the walking target process. This paper presents a hardware processing platform to TMS320DM6437 digital signal processor as the core processing chip, and an improved Houg...

This article explains an approach to further enhance the detection of geometric primitives namely straight lines, based on the spline filter contour decomposition method as shown in [1]. The aim is to split complex features into simple primitives for which further processing steps will lead to automated measurement results. Thus the inspection plan generated is reusable without employing additi...

The Hough transform is a robust method for detecting discontinuous patterns in noisy images. When it is applied to the detection of a straight line, represented by the normal parameters, the transform provides only the length of the normal and the angle it makes with the axis. The transform gives no information about the length or the end points of the line. A few authors have suggested algorit...
