Hello, I need some help. I have a project to create animation of an image mooving by some points of two arrays X and Y. This two arrays define some curve. I can put the background image and another one on top of it. But I can't think of a way to animate it. I tried every think I could think of but nothing is satisfactory ednouth. Can some one help me. If you require some code I could provide you. Thank you in advance!

Here's something simple that works - though it's not elegant or efficient:
% image data
bigIm = imread('street1.jpg');
smallysize = 50;
smallxsize = 70;
smallIm = bigIm(188:188+smallysize-1, 177:177+smallxsize-1, :);
% trajectory data
trajy = 400:-5:100;
trajx = trajy;
% animated display
for step = 1:length(trajx)
displayIm = bigIm;
displayIm(trajy(step):trajy(step)+smallysize-1, ...
trajx(step):trajx(step)+smallxsize-1, :) = smallIm;
imshow(displayIm);
pause(0.2);
end
