I have overlay one RGB image on the top of another RGB image. Result attached. I have issue with the resulting image, The person in the image seems very transparent w.r.t background. How can i control the transparency of the background image and foreground image. I have overlay the image using imfuse(A,B,'blend'). However, i can control the transparency to some extent using set(A, 'Alpha', alphadata), but i don't know how can i save those image

What is your actual question? "How can i control the transparency" and "i can control the transparency to some extent" sound confusing.

C = imfuse(A,B,'blend');
imwrite(C, 'YouImage.png');
Or perhaps you want:
alpha = 0.6;
C = alpha * A + (1 - alpha) * B;
imwrite(C, 'YouImage.jpg');

Hi Simon, imfuse(A,B,'blend') - blends two images successfully. However, the output image has some part of the image in the original RGB and some part dull region. Is there any way, we can make this dull region look like original one?
imfuse(A,B,'diff') - does it in grayscale.I am looking for something like that with 'blend' method.
Any ideas?
Attached is the image for your reference.
