MATLAB: Calculate entropy of an MR image entropyMATLAB I have to calculate entropy of mr image. I used both methods but it gives different ans… Can anyone help?? % Find entropy E = entropy(realimg(:)); % lg = log2(sum(realimg(:))); en = -sum(realimg(:).*log2(realimg(:))); Best Answer Simply do>> edit entropy.mto discover what their formula is and how it differs from yours. It will be obvious. Related SolutionsMATLAB: Entropy ROI Copy the points within the ROI in to vector and calculate the entropy of the vector. (With practice and logical indexing you will find it is not necessary to do the copying explicitly.)
