Buffering mechanism for camera-based gesturing

摘要

A method can include buffering video data to a buffer that includes a buffer capacity that corresponds to a video time interval; sampling video data at a sampling rate of at least once per video time interval; processing the sampled video data for gesture evidence; and, responsive to gesture evidence in the sampled video data, processing the buffered video data for additional gesture evidence. Various other apparatuses, systems, methods, etc., are also disclosed.

1. A method comprising:
buffering video data to a buffer that comprises a buffer capacity that corresponds to a video time interval that exceeds a sum of a longest gesture time interval and a recognition time interval for processing sampled video data for gesture evidence; sampling video data at a sampling rate of at least once per video time interval wherein the sampling rate comprises a frame sampling rate, wherein the buffering comprises buffering video data at a frame buffering rate, and wherein the frame buffering rate exceeds the frame sampling rate; processing the sampled video data for gesture evidence; and responsive to recognition of gesture evidence in the sampled video data, processing the buffered video data for additional gesture evidence.
