I will show you how to copy Part of image A to a certain position of image B
clc;clear
A = imread('Lena.jpg');
A = imresize(A,[200,200]);
imshow(A)
B = uint8(ones(600,600,3)*255); % create an empty image to get the copy from A
figure(1); clf; imshow(B)
title('Empty white image: the target image')
% copy Part of image A to image B
copyLen = 160; copyWid = 120;
copyPosAx = 11; copyPosAy = 31; % the pos coordinate
copyPosBx = 21; copyPosBy = 21;
% copy for the first time
B = imcopy(A, B, [copyPosAx, copyPosAy], [copyPosBx, copyPosBy], [copyLen, copyWid]);
figure(2); clf; imshow(B); title('After copy once')
copyPosBx = 201; copyPosBy = 201; % change the copy position of image B
% copy for the second time
B = imcopy(A, B, [copyPosAx, copyPosAy], [copyPosBx, copyPosBy], [copyLen, copyWid]);
figure(3); clf; imshow(B); title('After copy twice')
copyPosBx = 391; copyPosBy = 301; % change the copy position of image B
% copy for the third time
B = imcopy(A, B, [copyPosAx, copyPosAy], [copyPosBx, copyPosBy], [copyLen, copyWid]);
figure(4); clf; imshow(B); title('After copy third time')
The imcopy function is used for three times, after that, you can see how Lena's profile show in a white image with 3 times
