there is a formula in the following article:

Article link
page 503: Levine and Nazif

where simply it does the following:

ListOfClasses = [c1,c2,c3,...,cn], and where ci = [value1,value2,...,valuen]

so it does the intra-region uniformity, the closer to 1 the better the result.

Well what is really disturbing is that i cannot fix it while working with vectors instead of values:

ListOfClasses = [c1,c2,c3,...,cn], and where ci = [v1,v2,...,vn] where v = VECTOR

and where vi = [value1,value2,value3,...valuen]

Can you pls give me the pseudo-code for that algorithm with vectors!!

I am getting opposite results.
