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.

Digital or analog Hough transform? [PDF]

open access: yesPattern Recognition Letters, 1990
Abstract A variation of the Hough Transform that is aimed at detecting digital lines has been recently suggested. Other Hough algorithms are intended to detect straight lines in the analog pre-image. These approaches are analyzed and compared in terms of the relation between the achievable resolution and the required number of accumulators, using a ...

INTERIOR RECONSTRUCTION USING THE 3D HOUGH TRANSFORM [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Laser scanners are often used to create accurate 3D models of buildings for civil engineering purposes, but the process of manually vectorizing a 3D point cloud is time consuming and error-prone (Adan and Huber, 2011). Therefore, the need to characterize
