how to control the position of an image inside another one?

10 views (last 30 days)
Hi, I need your help please. I'm working in Matlab and I have tow images one with size 256*256 and the other one with size 64*64. I want to embed the small image into the first one but i would like to control the position of the embedding process. For example having the small image in the corner of the big image and then I want to changing in the middle ... do you have any idea how ? thank you

Youssra - suppose that you have a red and a blue image
redImg = uint8(zeros(256,256,3));
redImg(:,:,1) = uint8(255);
blueImg = uint8(zeros(64,64,3));
blueImg(:,:,3) = uint8(255);
To embed the smaller into the larger, say in the top left corner, you could do
redImg(1:64,1:64,:) = blueImg;
image(redImg);
Note how we assign the blueImg matrix of dimension 64x64x3 into the appropriately sized portion (same dimension) of the redImg matrix.
