Claim One:
1. A computer-implemented method of enabling gesture input to a computing device, comprising: setting a threshold number of pixels for a processor of the computing device to differentiate background objects from foreground objects; capturing image information using a pair of cameras of the computing device configured for stereoscopic image capture, a first camera of the pair of cameras capturing a first set of the image information and a second camera of the pair of cameras capturing a second set of the image information; analyzing the image information, using the processor of the computing device and the threshold number of pixels set prior to capturing image information, to determine that a first object is a background object where a difference in position between a first location of a reference point on the first object in the first set of image information and a second location of a corresponding reference point on the first object in the second set of image information represents less than the threshold number of pixels; determining that a second object in the image information is one or more foreground objects where a difference in position between a first location of a reference point on the second object in the first set of image information and a second location of a corresponding reference point on the second object in the second set of image information is at least the threshold number of pixels; and providing the image information that includes the second object to at least one gesture recognition process, the second object including one or more foreground objects.
