my problem is solved now.
But now i am stuck in one problem, let suppose for a histogram i calculated some min. class value, & want to know at which gray level..
like here: http://www.labbookpages.co.uk/software/imgProc/otsuThreshold.html
min. within class variance is 0.4909, BUT HOW CAN I KNOW IT IS ON WHICH LEVEL i.e. 1 or 2 or 3 or 4 or 5?
Actually i want this for larger images. i.e. to know at which level the variance is min.?
please help me out.
