FingerTemplate Class

Namespace: id3.Finger

Definition

Represents a finger template.

Properties

Name	Type	Description
captureDeviceCertificationList	FingerCaptureDeviceCertificationList	Certification(s) of the device used to the capture the finger image that the template was derived from.
captureDeviceTechnology	FingerCaptureDeviceTechnology	Technology of the device used to the capture the finger image that the template was derived from, as defined in ISO/IEC 19794-2:2011.
captureDeviceType	int	Capture device type identifier that identifies the product type that created this finger template.
captureDeviceVendorId	int	Capture device vendor identifier.
cbeffProductId	int	CBEFF product ID as registered with the IBIA (www.ibia.org).
dataFormats	FingerDataFormats	Fingerprint data formats information: minutiae, minutia embeddings and finger embedding formats.
extendedData	byte[]	Extended data of the finger template. Optional. Usually contains proprietary information that is useful for matching.
horizontalResolution	int	Horizontal resolution of the minutiae coordinate system. Be careful, setting this field does update the minutiae! Use Rescale for this purpose.
imageHeight	int	Size of the image that the template was derived from in the y direction (in pixels).
imageWidth	int	Size of the image that the template was derived from in the x direction (in pixels).
impressionType	FingerImpressionType	Impression type of the finger image that the template was derived from.
minutiaList	FingerMinutiaList	List of minutiae.
position	FingerPosition	Finger position of the template as defined in ANSI/NIST-ITL 1-2011.
quality	int	Quality of the created template. In the range [0;100] U {-1}, 100 being maximum quality and -1 meaning ‘not computed’.
qualityAlgorithmId	int	Quality algorithm identifier (including version) as assigned by the vendor.
qualityAlgorithmVendorId	int	Quality algorithm vendor identifier as registered with the IBIA (www.ibia.org).
ridgeEndingType	int	Method used to determine the location of a ridge ending with respect to the ISO/IEC 19794-2:2011. 0 indicates that the minutia was located at the intersection of 3 valleys, 1 means that it was located using the ridge skeleton endpoint.
verticalResolution	int	Vertical resolution of the minutiae coordinate system. Be careful, setting this field does update the minutiae! Use Rescale for this purpose.
viewNumber	int	Number of the view. Mostly useful for lists with multiple views of the same finger position.
