Realization of an efficient line detection by askant glance camera vision system using extended Hough transform

We propose a new vision mechanism which can saccadicly move its fixation point for detecting straight lines within the image frame. This system, askant glance camera vision (AGCV) system, can extract straight lines precisely around the fixation point and rather coarsely at the periphery of the fixation point. This camera system works in such a way that the fixation point catches the moving object by the information of the center of gravity of edges, and the edges of the moving object can be extracted better than the edges of the stationary object. This system demonstrates a model of the center fine/peripheral-coarse characteristics of human vision. This system is constructed by a slab-system which uses extended Hough transform functions and another subsystem which tracks an object and shifts its fixation point to the center of gravity. In this paper, we show some experimental results to show the performance of AGCV system
