Patent ID: 8730157

Claim:
A hand pose recognition method comprising: capturing, with one or more sensors, an image frame of an input hand pose; determining an initial hand pose estimate for the input hand pose; performing iterations, each iteration comprising: identifying a residue for a current hand pose estimate based upon data values for the input hand pose and data values for the current hand pose estimate, wherein the initial hand pose estimate serves as the current hand pose estimate during a first one of the iterations; and determining a current hand pose estimate based upon the input hand pose and the residue from the previous current hand pose estimate, comprising identifying residue based feature vectors that best match the residue from a general library of feature vectors and adding the identified residue based feature vectors to candidate feature vectors of the current hand pose estimate to form iteration feature vectors; outputting a hand pose estimate for the image frame of the input hand pose based upon results from the iterations; and generating one or more control signals, based upon the first image frame hand pose estimate, wherein the input hand pose is transformed to one or more control signals.
