Patent ID: 8755568

Claim:
A method of controlling an electronics device via hand gestures, comprising: detecting, via an image processing module of the electronics device, a bare-hand position via a camera input based upon a detected sequence of bare-hand positions; determining whether the bare-hand position has been detected for a threshold duration of time; identifying the detected bare-hand position from a vocabulary of hand gestures by: measuring brightness gradients in multiple directions across a plurality of images captured by the camera; generating image pyramids from measured brightness gradients of the extracted hand gesture; extracting pixel intensity/displacement features and scale invariant feature transform (SIFT) features using the generated pyramids; applying a cascade filter in association with extracting the pixel intensity/displacement features and the SIFT features from the generated image pyramids; classifying a hand pose type using a trained multiclass support vector machine (SVM); and determining the hand gesture by a distance calculation that calculates and selects a closest gesture in the vocabulary of hand gestures, where the closest gesture comprises a gesture with hand joints closest to the hand joints in the vocabulary of gestures; where the identified bare-hand position comprises a hand gesture associated with powering on the electronics device; and controlling, in response to determining that the bare-hand position has been detected for the threshold duration of time, the electronics device in response to the identified bare-hand position by powering on the electronics device.
