Overlaying a partially transparent binary over an RGB image?

As the title suggests, I'm trying to overlay a binary mask over an RGB image to verify segmentation. How do I make the binary mask partially transparent so that I can see what's underneath?

Thank you.

It depends on what you are doing. Please post, what "overlay a binary mask" means as Matlab code.

See the example given by the leader of the Image Processing team:

This is the blog to which I referred to find the solution.

If you are creating an image object, such as by image() or imagesc() or imshow(), then set the AlphaData property of the overlay image.
