Functions

func DetectionResult

func DetectionResult(in *matrix.M) *types.DetectionResult

DetectionResult applies all the available image processing algorithms to finally extract a list of minutiae. Reference frame is detected too.

func Frame

func Frame(binarizedSegmented *matrix.M) types.Frame

Frame detects the boundaries of the fingerprint and establishes a reference point and the angle of such reference point.

func Minutia

func Minutia(skeleton *matrix.M, filteredDirectional *matrix.M, segmented *matrix.M) types.MinutiaeList

Minutia retrieves fingerprint features from a skeletonized image. Each feature angle is obtained from the filtered directional image. Features outside the fingerprint itself are removed by checking against the segmented image, that tells us what is fingerprint from background.
