hi, my project is related to watermarking i have embedded an image over another as a watermark by using the code

i= imread(boat.jpg);
j=imread(image.jpg);
j=imresize(j,0.2)
i((size(i,1)-size(j,1)+1):end, (size(i,2)-size(j,2)+1):end,1:end) = j

fliplr() or flipud() the image before embedding the watermark in it; then fliplr() or flipud() the post-watermarked image back to its original orientation.
