cover another image by multiple image with exactly position ?

1 view (last 30 days)
Dear All,
I am doing my study thesis and I got problem that I don't know how to overlay current image to other image with exactly position.
The position was generate when i detect the centroid. (it can be seen in the stat variable in workspace after run my code)
Could any expert help me please ?
another image is 'Original.jpg' that i attached to this post
This is my code:
Ibw = imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/999460/finalmask.png');
stat = regionprops(Ibw,'Centroid');
imread(("https://www.mathworks.com/matlabcentral/answers/uploaded_files/999465/original.jpg"));
imshow(imread(("https://www.mathworks.com/matlabcentral/answers/uploaded_files/999465/original.jpg")))
hold on;
N=numel(stat);
for i=1:N
stat(i).BoundingBox=[stat(i).Centroid-32.5, 63,63];
plot(stat(i).Centroid(1),stat(i).Centroid(2),'+',LineWidth=2);
end
hold off
I2=imread("https://www.mathworks.com/matlabcentral/answers/uploaded_files/999465/original.jpg")
subimages=arrayfun(@(s)imcrop(I2,s.BoundingBox), stat,'uni',0); %You can use a new image here
montage(subimages,'Back','w','Bor',0)
for k = 1:N
b{k}=cell2mat(subimages(k,1))
filename=sprintf('image0%d.jpg',k)
imwrite(b{k},filename)
end
Thanks and Regards
Han

Try imoverlay and see if that's what you want.

If you don't have a binary image then imoverlay would not be what you want. If you have gray scale images then you may just want to paste them onto the image, covering up what was there before. See attached demo.
