Types

type Data 

type Data struct {
	Id         string
	Descriptor goFace.Descriptor
}

Data descriptor of the human face.

type Face 

type Face struct {
	Data
	Rectangle image.Rectangle
}

Face holds coordinates and descriptor of the human face.

type Recognizer 

type Recognizer struct {
	Tolerance float32

	UseCNN              bool
	UseGray             bool
	UseFastJPEGEncoding bool
	Dataset             []Data
	// contains filtered or unexported fields
}

A Recognizer creates face descriptors for provided images and classifies them into categories.

func (*Recognizer) AddImageBytesToDataset

func (*Recognizer) Classify 

func (_this *Recognizer) Classify(path string) ([]Face, error)

Classify returns all faces identified in the image. Empty list is returned if no match.

func (*Recognizer) ClassifyFaces 

func (_this *Recognizer) ClassifyFaces(faces []goFace.Face) ([]Face, error)

Classify from a list of recognized faces.

func (*Recognizer) ClassifyMultiples

func (*Recognizer) CleanDataset 

func (_this *Recognizer) CleanDataset()

CleanDataset cleans dataset

func (*Recognizer) Close 

func (_this *Recognizer) Close()

Close frees resources taken by the Recognizer. Safe to call multiple times. Don't use Recognizer after close call.

func (*Recognizer) DrawFaces 

func (_this *Recognizer) DrawFaces(Path string, F []Face) (image.Image, error)

DrawFaces draws the faces identified in the original image

func (*Recognizer) DrawFaces2 

func (_this *Recognizer) DrawFaces2(Path string, F []goFace.Face) (image.Image, error)

DrawFaces2 draws the faces in the original image

func (*Recognizer) GrayScale 

func (_this *Recognizer) GrayScale(imgSrc image.Image) image.Image

GrayScale Convert an image to grayscale

func (*Recognizer) Init 

func (_this *Recognizer) Init(path string) error

Init initialise a recognizer interface.

func (*Recognizer) LoadImage 

func (_this *Recognizer) LoadImage(Path string) (image.Image, error)

LoadImage Load an image from file

func (*Recognizer) RecognizeMultiples 

func (_this *Recognizer) RecognizeMultiples(path string) ([]goFace.Face, error)

RecognizeMultiples returns all faces found on the provided image, sorted from left to right. Empty list is returned if there are no faces, error is returned if there was some error while decoding/processing image. Only JPEG format is currently supported.

func (*Recognizer) RecognizeMultiplesFromBytes 

func (_this *Recognizer) RecognizeMultiplesFromBytes(imgBytes []byte) ([]goFace.Face, error)

func (*Recognizer) RecognizeMultiplesFromImage 

func (_this *Recognizer) RecognizeMultiplesFromImage(img image.Image) ([]goFace.Face, error)

func (*Recognizer) RecognizeSingle 

func (_this *Recognizer) RecognizeSingle(path string) (goFace.Face, error)

RecognizeSingle returns face if it's the only face on the image or nil otherwise. Only JPEG format is currently supported.

func (*Recognizer) RemoveFromDataset 

func (_this *Recognizer) RemoveFromDataset(id string)

func (*Recognizer) SaveDataset 

func (_this *Recognizer) SaveDataset(Path string) error

SaveDataset saves Dataset data to a json file

func (*Recognizer) SaveImage 

func (_this *Recognizer) SaveImage(Path string, Img image.Image) error

SaveImage Save an image to jpeg file

func (*Recognizer) SetSamples 

func (_this *Recognizer) SetSamples()

SetSamples sets known descriptors so you can classify the new ones.
