Calculates normalized histogram intersection norm.
| Name | Type | Description | |
|---|---|---|---|
 |
inHistogram1 | Histogram | First input histogram |
|
inHistogram2 | Histogram | Second input histogram |
 |
outHistogramIntersection | Double |
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
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
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. |
Complexity Level
This filter is available on Basic Complexity Level.
