## Detailed Description

A norm based cost extraction. :

## Member Function Documentation

## § getNormFlag()

virtual int cv::NormHistogramCostExtractor::getNormFlag | ( |  | ) | const
| pure virtual

Python:
| retval | = | cv.NormHistogramCostExtractor.getNormFlag( |  | )

## § setNormFlag()

virtual void cv::NormHistogramCostExtractor::setNormFlag | ( | int | flag | ) |
| pure virtual

Python:
| None | = | cv.NormHistogramCostExtractor.setNormFlag( | flag | )
