Witryna5 gru 2024 · When you permute (siz_img, [3 1 2 4]) then the second dimension would move to the third dimension, so the output would be 1 x 1 x length (siz_img) = 1 x 1 x 2. You then try to imshow () that 1 x 1 x 2, which fails because imshow () can only handle arrays that are either 2D or 3D with the third dimension being length 3. Witryna2 gru 2024 · phref = linspace (0,14,29); [~,idx] = min (sum ( (CT-meancolor).^2,2)); phref (idx) % estimated pH. Unless the goal of this effort is to specifically perform this task by image analysis, it may be a lot easier and more consistent to get an inexpensive pH meter (depending on the range of what you need to measure).
