Histograms carry information about frequencies of numeric values. In Aurora Vision Studio histograms are internally represented as sequences of Double values together with additional meta-information:

• DomainStart : Real – minimum value for which frequency is measured
• BinSize : Real – determines precision of the histogram

It is worth mentioning that infinite/NaN values in the bins of the histogram can cause filters to compute incorrect results and thus such values should be used with caution.
