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
