Interface Detector

detector.go:26–30

Detector detects regions of interest in a raw pixel buffer. Implementations are free to perform any kind of detection (faces, objects, text boxes, etc.) — the only contract is the coordinate space. imagePath identifies the source image (e.g. URL path) and is used as a cache key by implementations t

// Returned regions must use normalised coordinates in [0.0, 1.0] relative to
// the image width / height stored in blob.
type Detector interface {
	Startup(ctx context.Context) error
	Detect(ctx context.Context, imagePath string, blob *Blob) ([]DetectorRegion, error)
	Shutdown(ctx context.Context) error
}

// DetectorAdder is implemented by processors that accept one or more Detectors.
// imagorface and other detector plugins use this interface to wire a detector
