Method Documentation

addFeature:dependencies:

- (void) addFeature:		(nullable id< BNBFeature >)	feature
dependencies:		(nonnull NSSet< NSNumber * > *)	dependencies

clear

- (void) clear

clear input and output buffers and pipeline state, also clean cached features

create:

getFeatureId:

+ (int64_t) getFeatureId:

(BNBFeatureId)

feature

pause

- (void) pause

pause the recognizer

popFrameData:

- (BOOL) popFrameData:

(nullable BNBFrameData *)

outputFrameData

process:

- (void) process:

(nullable BNBFrameData *)

removeFeature:

setFeatures:

features

setMaxFaces:

- (void) setMaxFaces:

(int32_t)

num

sets maximum allowed face results, if face tracking feature is present

setOfflineMode:

- (void) setOfflineMode:

(BOOL)

on

setUseFutureFilter:

- (void) setUseFutureFilter:

(BOOL)

on

Set future frame filtrarion mode.

Produce smoother recognition result (anti jitter), however adds inconsistency in push'ed/pop'ed frames (one frame lag) Applied only in push_camera_frame/pop_frame_data methods, when offline mode is disabled. Example: push frame 1 - pop frame 1, push frame 2 - pop frame 1, push frame 3 - pop frame 2, ...

setUseFutureInterpolate:

- (void) setUseFutureInterpolate:

(BOOL)

on

Set future frame interpolation mode.

Produce faster recognition result (skip even frames), however adds inconsistency in push'ed/pop'ed frames (one frame lag) Applied only in push_camera_frame/pop_frame_data methods, when offline mode is disabled. Example: push frame 1 - pop frame 1, push frame 2 - pop frame 1, push frame 3 - pop frame 2, ...

start

- (void) start

start the recognizer

stop

- (void) stop

pause + clear
