چکیده

In the paper, a hybrid image processing approach – the adaptive morphological Hough transform AMHT – is developed and applied to detect straight line tracks in the volumetrical images produced by particle collisions in the ATLAS detector. The approach combines components of the adaptive Hough transform (i.e. the resolution refinement of the parameter space) and the morphological Hough transform (i.e. using a morphological mask to increase the chance for detecting the correct peak in Hough space). Experimental results show that the new AMHT method improves the detection efficiency from 86% to 89% while maintaining the timing requirements.

Iris localization by means of adaptive thresholding and Circular Hough Transform

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

A Cascaded Hough Transform as an Aid in Aerial Image Interpretation

Cartography and other applications of remote sensing have led to an increased interest in the (semi-)automatic interpretation of structures in aerial images of urban and suburban areas. Building delineation and 3D reconstruction is a good case in point. Although urban and suburban areas are particularly challenging because of their complexity, the degree of regularity in such man-made structure...

Detection of Vanishing Points Using Hough Transform for Single View 3D Reconstruction

Single View Reconstruction (SVR) is a technique to reconstruct three-dimensional scenes or objects of interest from a single image. Unlike traditional (multi-view) close-range photogrammetry, SVR does not require camera parameters for obtaining 3D coordinates of the targets. A common approach for SVR is to establish the 3D metrology based on vanishing points from a single image with perspective...
