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 % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% output
% hough_space:参数空间,h(a,b,r)表示圆心在(a,b)半径为r的圆上的点数
% hough_circl:二值图像,检测到的圆
% para:检测到的圆的圆心、半径
