FIL.HistogramIntersection

Calculates normalized histogram intersection norm.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void HistogramIntersection
(
	FilNet.Histogram inHistogram1,
	FilNet.Histogram inHistogram2,
	out float outHistIntersection
)

Parameters

Name Type Range Default Description
inHistogram1FilNet.HistogramFirst input histogram.
inHistogram2FilNet.HistogramSecond input histogram.
outHistIntersectionfloat

Description

The operation computes the normalized histogram intersection defined as: \[\frac{ {\sum\limits_{j = 1}^n {\min \left( {inHistogram{1_j},inHistogram{2_j} } \right)} } }{ {\sum\limits_{j = 1}^n {inHistogram{2_j} } } }\]

Remarks

  • Data sets for the input histograms cannot be empty, otherwise an error with appropriate description occurs,
  • inHistogram1 and inHistogram2 must have the same BinSizes, otherwise an error with appropriate description occurs.

Errors

List of possible exceptions:

Error type Description
DomainError Empty histogram on input in HistogramIntersection.
DomainError Input histogram formats are not the same in HistogramIntersection.
DomainError Negative value in a histogram in HistogramIntersection.
