Class InputFrameToFeedbackFrameAdapter

Namespace

easyar

Input frame to feedback frame adapter. There is an input frame input port, a historical output frame input port, and a feedback frame output port, used to combine input frames and historical output frames into feedback frames, and pass them to algorithm components that require feedback frames as input, for example ImageTracker. Each time an input frame is input, it combines with the historical output frame from the previous input to synthesize a feedback frame. If no historical output frame has been input, the historical output frame in the feedback frame is empty. InputFrameToFeedbackFrameAdapter occupies 1 camera buffer. The camera's setBufferCapacity should be set to no less than the number of camera buffers occupied by all components. All members of this class are thread-safe.
