Types

type Detector

type Detector struct {
	// contains filtered or unexported fields
}

Detector is an abstraction for a motion detector

func NewMotionDetector

func NewMotionDetector(camID int, winTitle string, onDetect func()) (*Detector, error)

NewMotionDetector is the constructor for a Detector

func (*Detector) Close

func (d *Detector) Close()

Close handles closing gocv resources

func (*Detector) SnapshotJPG

func (d *Detector) SnapshotJPG() ([]byte, error)

SnapshotJPG returns a jpg encoded byte slice containing the latest image taken from the video capture device

func (*Detector) Start

func (d *Detector) Start() error

Start initializes the motion detector

func (*Detector) Status

func (d *Detector) Status() string

Status returns the status of the detector
