Hi,

I tried HistogramNode in DMIP .Its working ok on single core platform(p4)
But same code when I am running on multocore[i7,dual core ] .Histogram values are not at all matching .
Histogram sum is not coming out equal to size (height*width) of image.
Is it the known reason that DMIP handle histogram parallely?
I experimented this fact umpteen times But still the same

Is there any way to get around with it? Any urgent reply would be graetly appreaciated

Thanks in advance ,
Kishor
