Normally, there is no problem, if we load two images in jpg formats, and insert one image to another as logo. But due to background and boarders, we need to insert png image. the output is attached
** how to handle png images.
As we know that png images have no backgroud, but once they are loaded in matlab, background turns into black. how to handle the background.
consider following image,
img1 = imread('1.jpg');
logo = imread('logo.png');
img1(1:size(logo,1), 1:size(logo,2), :) = logo;
imshow(img1)

@king umar, is your question about compositing two images with one having associated transparency info (i.e alpha blending)?

@Guillaume I wrote that comment on Chrome in Android (just like this one). It does seem strange.

If you want to prevent overwriting the underlying image for some pixels, you can use a logical mask to only overwrite some pixels.
