Low-latency gesture detection

A gesture recognition method comprising:

• receiving, at a processor, an input stream of image frames depicting an articulating entity;
• computing features from individual ones of the image frames by computing frame level features and aggregating at least some of the frame level features;
• sending the computed features to a trained machine learning system;
• and
• receiving in response at least one gesture class from a plurality of possible gesture classes;
• wherein the individual ones of the image frames are fewer than a number of the image frames depicting a complete gesture of the gesture class made by the articulated entity.

A gesture recognition engine comprising:

• a processor arranged to receive an input stream of image frames depicting an articulating entity;
• and
• an instance level representation engine arranged to compute features from individual ones of the image frames and to send the computed features to a trained machine learning system;
• the processor arranged to receive in response at least one gesture class from a plurality of possible gesture classes;
• wherein the individual ones of the image frames are fewer than a number of the image frames depicting a complete gesture of the gesture class made by the articulated entity.
