Dear Mathwork community and support team,
I am a novice Matlab image processing user. I am trying to find an appropriate code to overlay two images such that the top image overlay is opaque in the center and uniformly fades or blurs to completely transparent in each direction show the bottom image. I looked at a similar discussion on using alpha data but I was unable to understand how to apply the fade / blur and transparent algorithm using alpha data and repmat functions in all directions of the image(<http://www.mathworks.com/matlabcentral/answers/100086-how-do-i-superimpose-images-in-matlab)>.
Please can someone with good understanding of matlab image processing help me with this question.
Thanks a lot for the help.
Kind Regards,
Vidya

Try imfuse() or imshowpair().

You can apply a weighted average
w = 0.25; % or whatever...
newImage = w*double(image1) + (1-w) * double(image2);
imshow(newImage, []);
