Line Detection Using Radon Transform [PDF]

open access: yesEngineering and Technology Journal, 2010
To extract features from digital images, it is useful to be able to find simpleshapes (straight lines, circles, ellipses, etc.).In order to achieve this goal, one can be able to detect a group of pixels that are ona straight line or a smooth curve.

A New Method for Crop Row Detection Using Unmanned Aerial Vehicle Images

open access: yesRemote Sensing, 2021
Crop row detection using unmanned aerial vehicle (UAV) images is very helpful for precision agriculture, enabling one to delineate site-specific management zones and to perform precision weeding.

Automatic Detection of Calibration Grids in Time-of-Flight Images [PDF]

open access: yes, 2014
It is convenient to calibrate time-of-flight cameras by established methods, using images of a chequerboard pattern. The low resolution of the amplitude image, however, makes it difficult to detect the board reliably.

Track Detection Algorithm Based on Trace Correlation Using Hough Transform

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. Track detection is one of the main tasks to be solved in trajectory processing. This task can be efficiently solved using the Hough Transform.

Measurement Method for Plane Transverse Vibration of Hoisting Steel Wire Rope by Hough Transform

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2021
To solve the difficulty that transverse vibration displacement of moving steel wire rope cannot be easily acquired, the present study proposes a method using Hough transform to measure plane transverse displacement of hoisting rope.

The cascaded Hough transform

open access: yesProceedings of International Conference on Image Processing, 2002
When using the original slope-intercept parameterisation 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.

Feature Extraction of Gear Fault Signal Based on Sobel Operator and WHT

open access: yesShock and Vibration, 2013
Taking Wigner-Ville distribution of gear fault signal as a picture, Sobel operator was applied for edge detection of picture and then Hough transform was used to extract signal feature.

Combined Randomized-Local Hough Transform versus UpWrite Transform in stamp detection [PDF]

open access: yesComputer Science Journal of Moldova, 2003
The conventional Hough Transform used for detection of objects with known shape and size has proved its robustness. One typical task for this transform can be the detection of stamp(s) on an envelope.

Using gradient information to enhance the Progressive Probabilistic Hough Transform [PDF]

open access: yes, 2000
In this paper we look at the benefits to be gained in using gradient information to enhance the progressive probabilistic Hough transform (PPHT). It is shown how using the angle information in controlling the voting process and in assigning pixels ...
