System and Method of Hand Gesture Detection

A non-transitory computer-readable storage medium, including instructions, the instructions, when executed by one or more processors of a computing system, cause the processors to perform operations comprising:

• identifying, using a first image processing process, one or more first regions of interest (ROI) in a first input image, wherein the first image processing process is configured to identify first ROIs corresponding to a predefined portion of a respective human user in an input image;
• providing a downsized copy of a respective first ROI identified in the first input image as input for a second image processing process, wherein the second image processing process is configured to identify one or more predefined features of a respective human user and to determine a respective control gesture of a plurality of predefined control gestures corresponding to the identified one or more predefined features;
• and
• in accordance with a determination that a first control gesture is identified in the respective first ROI identified in the first input image, and that the first control gesture meets preset first criteria associated with a respective machine, triggering a control operation at the respective machine in accordance with the first control gesture.
