How to change transparency and color of overlay using imshow?
35 views (last 30 days)
I have a matrix with MRI data that I can plot using imshow in a gray-scale image. Using segmentation I created a mask of part of the brain and I want to overlay this mask (containing only 0 and 1) over my original image. I would like to be able to change the transparancy and color of this mask overlay. Can someone help me with this?
