function [hough_space,hough_circle,para] = hough_circle(BW,step_r,step_angle,r_min,r_max,p) %% input% BW:二值图像;% step_r:检测的圆半径步长% step_angle:角度步长,单位为弧度% r_min:最小圆半径% r_max:最大圆半径%p:以p*hough_space的最大值为阈值,p取0,1之间的数...
The use of the Hough transform as a feature space is investigated. The Hough space is used directly, along with some new efficient transformations, for the determination of translation and rotation parameters of two-dimensional objects composed of straight-line segments. New methods to implement the...

However, many small FPGAs are incapable of implementing the LHT due to the large memory requirement of the Hough Parameter Space (HPS). This paper presents a memory-efficient architecture of the LHT named the Angular Regions - Line Hough Transform (AR-LHT). We present a suitable FPGA ...
Under heavy clutter conditions, Hough transform has been used to initiate in the two dimensional space, but it has not been used in the three dimensional space yet. The paper presents a new Hough transform (HT) and logic based track initiator in the three dimensional space. First two projecti...
