在这里,我开发了一些用于在图像上绘制框的代码,但我得到
了不同图像上的框。所有的盒子都应该在同一个图像中。请帮助我。
video = VideoReader('parking video1.mp4');
I = read(video,1);
J = read(video,200);
a=104; b=73;
c=104; d=515;
count=0;count1=0;count2=0;
total=10;
for i=1:5
im1=imcrop(I,[a,b,283, 448]);
im3=imcrop(J, [a,b,283, 448]);
Background1 =abs(im1 - im3);
grayImage1 = rgb2gray(Background1);
% Convert to gray level
thresholdLevel1 = graythresh(grayImage1);
% Get threshold.
binaryImage1 = im2bw( grayImage1, thresholdLevel1);
% Do the binarization
binaryImage1 = bwareaopen(binaryImage1,1000);
ak=bwarea(binaryImage1);
figure, imshow(J);
hold on;
if ak>0
rectangle('Position',[a,b,283, 448],'Edgecolor', 'r');
else
rectangle('Position',[a,b,283, 448],'Edgecolor', 'g');
end
a=a+280;
end
