Member Enumeration Documentation

Kind

enum class SlapSegIII::SlapImage::Kind

strong

Kind of slap image.

Enumerator

ThreeInch	Identification Flats (FRGP 13, 14, 15)
UpperPalm	Upper palm (FRGP 15, 26, 28)
FullPalm	Full palm (FRGP 21, 23)

Definition at line 99 of file slapsegiii.h.

CaptureTechnology

enum class SlapSegIII::SlapImage::CaptureTechnology

strong

Friction ridge capture technology.

Enumerator
Unknown	Unknown.
ScannedInkOnPaper	Scanned ink on paper.
OpticalTIRBright	Optical, total internal reflection, bright field.

Definition at line 112 of file slapsegiii.h.

Orientation

enum class SlapSegIII::SlapImage::Orientation

strong

Hand orientation being segmented.

Enumerator
Right	Right hand.
Left	Left hand.
Thumbs	Two thumbs.

Definition at line 123 of file slapsegiii.h.

Deficiency

enum class SlapSegIII::SlapImage::Deficiency

strong

Reasons that a SlapImage cannot be reliably segmented.

Enumerator
Artifacts	Moisture/condensation "halos," "ghost" impressions, etc.
ImageQuality	Low contrast, over-inked, too much pressure, etc.
HandGeometry	Hand placed sideways, upside-down, or is overly-rotated in impressions where rotation is not expected.
Incomplete	Overwhelming majority of expected ridge structure is not present.

Constructor & Destructor Documentation

SlapImage() [1/2]

SlapSegIII::SlapImage::SlapImage

(

)

Default SlapImage constructor.

Definition at line 54 of file libslapsegiii.cpp.

SlapImage() [2/2]

SlapSegIII::SlapImage::SlapImage	(	const uint16_t	width,
		const uint16_t	height,
		const uint16_t	ppi,
		const Kind	kind,
		const CaptureTechnology	captureTechnology,
		const Orientation	orientation,
		const std::vector< std::byte > &	pixels
	)

SlapImage constructor.

Parameters

width	Width of the image.
height	Height of the image.
ppi	Resolution of the image in pixels per inch.
kind	The kind of capture employed to create the image.
captureTechnology	The capture technology used to create the image.
orientation	The orientation of fingers in the image.
pixels	width * height bytes of image data, with pixels.front() representing the top-left pixel and pixels.back() representing the bottom-right pixel. It is raw 8 bits/pixel grayscale image data, canonically coded as defined in ISO/IEC 19794-4:2005, section 6.2.

Member Data Documentation

width

uint16_t SlapSegIII::SlapImage::width {}

Width of the image.

Definition at line 192 of file slapsegiii.h.

height

uint16_t SlapSegIII::SlapImage::height {}

Height of the image.

Definition at line 194 of file slapsegiii.h.

ppi

uint16_t SlapSegIII::SlapImage::ppi {}

Resolution of the image in pixels per inch.

Definition at line 196 of file slapsegiii.h.

kind

Kind SlapSegIII::SlapImage::kind {}

The kind of capture employed to create the image.

Definition at line 198 of file slapsegiii.h.

captureTechnology

CaptureTechnology SlapSegIII::SlapImage::captureTechnology {}

The capture technology used to create the image.

Definition at line 200 of file slapsegiii.h.

orientation

Orientation SlapSegIII::SlapImage::orientation {}

The orientation of fingers in the image.

Definition at line 202 of file slapsegiii.h.

pixels

std::vector<std::byte> SlapSegIII::SlapImage::pixels {}

width * height bytes of image data, with pixels.front() representing the top-left pixel and pixels.back() representing the bottom-right pixel.

It is raw 8 bits/pixel grayscale image data, canonically coded as defined in ISO/IEC 19794-4:2005, section 6.2.

Note

To pass pixels to a C-style array, invoke pixel's data() method (pixels.data()).
