"rounding box" == "bounding box"?

I wonder what the purpose of this is, but here goes:
Image1 = imread('rice.png'); % conveniently is 256x256.
Image2 = uint8(zeros(8,8)); %Artificial image 2.
Image3 = Image1; Image3(1:8,1:8) = Image2; %change the indices 1:8 to wherever you want to put the Image2 in Image1;
You could add the bounding box, if that's what you mean, by manually adding rows and columns of black pixels around your Image2. Image2(1,:) = ones(size(Image2(1,:))); and so on for all the borders. Does this work?
