Follow-up Comment #9, bug #45333 (project octave): There is still a minor problem in a corner case: >> H(1) = 100; >> graythresh(H) warning: division by zero warning: called from graythresh>otsu at line 217 column 13 graythresh at line 186 column 35 warning: division by zero warning: called from graythresh at line 192 column 12 ans = NaN In Matlab the answer is zero. The problem is in the line: thresh{1} = double (thresh{1}) / (numel (ihist) - 1); since numel(ihist) is 1 _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?45333> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
