Tutorial: Generate BBox or Rectangle to locate the target obejct  

　　

 1 clc;close all;clear all;
 2 Img=imread(\'/home/wangxiao/Documents/files/Visual_Tracking/MDNet-CVPR2016/MDNet-master/attentionMap/Basketball/0001.png\');
 3 if ndims(Img)==3
 4     I=rgb2gray(Img);
 5 else
 6     I=Img;
 7 end
 8 I=im2bw(I,graythresh(I));
 9 [m,n]=size(I);
10 imshow(I);title(\'binary image\');
11 txt=get(gca,\'Title\');
12 set(txt,\'fontsize\',16);
13 L=bwlabel(I);
14 stats=regionprops(L,\'all\');
15 set(gcf,\'color\',\'w\');
16 set(gca,\'units\',\'pixels\',\'Visible\',\'off\');
17 q=get(gca,\'position\');
18 q(1)=0;%设置左边距离值为零
19 q(2)=0;%设置右边距离值为零
20 set(gca,\'position\',q);
21 for i=1:length(stats)
22     hold on;
23     rectangle(\'position\',stats(i).BoundingBox,\'edgecolor\',\'y\',\'linewidth\',2);
24     temp = stats(i).Centroid;
25     plot(temp(1),temp(2),\'r.\');
26     drawnow;
27 end
28 frame=getframe(gcf,[0,0,n,m]);
29 im=frame2im(frame);
30 imwrite(im,\'a.jpg\',\'jpg\');%可以修改保存的格式
