Changing image transparency seems simple enough, but when I try to do this to superimpose my PET and MR imaging data, I don't get good results. First image shows what I have now and second shows an example of correctly superimposed results done manually.
Would love some help with this issue and have included my code and the variables:
figure
for n = 1:10
subplot(2,5,n)
MRtr = imshow(Ven(1:156,1:156,n),[]);
hold on
PTtr = imshow(interpolatedPET(1:156,1:156,n)',[],Colormap=hot);
PTtr.AlphaData = 0.5;
end

Ran in:
You could use imfuse.
load workspaceoverlay.mat
figure
for n = 1:10
subplot(2,5,n)
% MRtr = imshow(Ven(1:156,1:156,n),[]);
% hold on
% PTtr = imshow(interpolatedPET(1:156,1:156,n)',[],Colormap=hot);
% PTtr.AlphaData = 0.5;
c = imfuse(Ven(1:156,1:156,n), interpolatedPET(1:156,1:156,n)');
imshow(c)
end
