[Insight-users] Histogram quantile

[sere f]

Dear All,

I want to calculate the 25th, 50th and 75 th percentile of the histogram of
my image.
I use
histogram->Quantile( 0, 0.25 )
histogram->Quantile( 0, 0.50 )
histogram->Quantile( 0, 0.75 )

They are not  reasonable value.
Do I miss something?

Thanks,

Serena.
