I have a mask with regions labeled with 1, 2 and 3. I have a 3D volume that I would like to calculate the mean of the pixels correspond to those regions.
I want to calculate the mean of the regions with number 1, number 2 and number 3 separately.
Is the following correct?
m = mean(volume(mask==1));
m = mean(volume(mask==2));
m = mean(volume(mask==3));
