color image histogram

[Cen_Rao]

I am using IPP 5.3

the document of ippi does not give enough information about.

ippiHistogramEven support multi-channel data, but my understanding is that it computes histogram individually for each channel. Therefore, it is really not a real color histogram. How can I know how many pixels are at color RGB(a,b,c) ?

Thanks a lot.

Documentation of the latest IPP 6.0 says that histogram calculated separately for each channel.
