Hi,
So I have a set (a stack?) of 2D images and I have them stored in a 3D array. I now want to compare pixel values throughout the images, so I would compare…
images(1,1,1), images(1,1,2), images(1,1,3) etc...
and then
images(1,2,1), images(1,2,2), images(1,2,3) etc...
So far I have…
for j = 1:length(dat) [img, map] = dicomread(char(dat(j,1))); images(:,:,j) = img; end
valsZ = cell(size(images, 3), 2); valsX = cell(size(images, 3), 2, size(images, 2));
for x = 1:size(images, 2) for z = 1:size(images, 3) imgVal = images(y,x,z); valsZ(z,:) = {z, imgVal}; end valsX(x,:,:) = {x, valsZ(1,:), valsZ(2,:)}; end
I think I would need to create a 4D array to store the pixel information so that I have a 2D array of pixel value and image number within a 3D array that defines which column the data is in and then a 4D array for which row the data is in.
At the moment I am getting a 'Subscripted assignment dimension mismatch' error for valsX. Any help would be great! Thanks!
