FACIAL FEATURES DETECTION USING TEXTURE HOUGH TRANSFORM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
The paper presents an original method for object detection. The “texture” Hough transform is used as the main tool in the search. Unlike classical generalized Hough transform, this variation uses texture LBP descriptor as a primitive for voting.

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.

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 Initiation Based on Parallel Hough Transform

open access: yesLeida xuebao, 2013
As a batch processing method, the Hough transform hardly overcomes the accumulation phenomenon of single-scan data sets for it gets confused with the time sequence information of measurements.

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.

Gradient based progressive probabilistic Hough transform [PDF]

open access: yes, 2001
The authors look at the benefits of exploiting gradient information to enhance the progressive probabilistic Hough transform (PPHT). It is shown that using the angle information in controlling the voting process and in assigning pixels to a line, the ...
