Classify returns class ID for the given descriptor. Negative index is returned if no match. Thread-safe.

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

Same as Recognize but accepts image path instead.

Same as RecognizeSingle but accepts image path instead.

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

makeError constructs Go error for passed error info.

Same as Classify but allows to specify max distance between faces to consider it a match. Start with 0.6 if not sure.

NewRecognizer returns a new recognizer interface. modelDir points to directory with shape_predictor_5_face_landmarks.dat and dlib_face_recognition_res

Recognize 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

From memory JPEG loader because dlib lacks one.

This example shows the basic usage of the package: create an recognizer, recognize faces, classify them using few known ones.

New creates new face with the provided parameters.

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