Variable Documentation

Mean

const char NFIQ2::Identifiers::QualityFeatures::RegionOfInterest::Mean[]

extern

Mean grayscale value of the number of 32x32 pixel regions having at least 1 pixel in the ROI.

CoherenceSum

const char NFIQ2::Identifiers::QualityFeatures::RegionOfInterest::CoherenceSum[]

extern

Sum of coherence values over all 16x16 pixel regions within the ROI.

CoherenceMean

const char NFIQ2::Identifiers::QualityFeatures::RegionOfInterest::CoherenceMean[]

extern

Average of coherence values over all 16x16 pixel regions within the ROI.

This is computed as RegionOfInterest::CoherenceSum / (number of 16x16 pixel regions that contain at least 1 pixel within the ROI).
