Types

type FingerPrint

type FingerPrint struct {
	Hash   []byte
	Images []string
}

FingerPrint is a fingerprint and the files associated with it

type FingerPrintCollection

type FingerPrintCollection struct {
	FingerPrints []FingerPrint
}

FingerPrintCollection is a collection of fingerprints

type FingerPrinter

type FingerPrinter interface {
	FingerPrint() ([]byte, error)
}

FingerPrinter specifies a value that can generate a practically-unique fingerprint for an image
