I have some cellular image, I generated a binary mask based on the time lapse result. Now I want to "burn" the mask to the original grey scale image with transparency so that I can check if the mask makes sense. The original image is a double precison, I used imoverlay(nomalize(A,'range'), Mask, [0.3 1 0.3]). My issue is that I cannot see anything underneath the mask. I there any way to make the maks transparent? Thanks.
