Claim:
1. A method for performing 2D gesture recognition, comprising: performing at least one scan on a portion of an input image with an object detector to detect a gesture therein and produce a first set of hits, wherein each hit in the first set of hits is associated with location indicia and size identifying a location in the input image at which the gesture is detected; and applying a filter to the first set of hits so as to remove at least one false positive hit contained therein; wherein applying said filter comprises applying a custom filter; and applying said custom filter comprises: defining an input window in said input image based at least in part on location indicia associated with at least one hit in said first set of hits; performing a scanning operation on at least a portion of the input window along at least one scan line to detect a plurality of luminance minima along said at least one scan line and produce a first set of luminance minima containing said plurality of luminance minima; determining which luminance minima in the first set of luminance minima exhibit significant luminance drop; and when at least one luminance minima exhibits significant luminance drop, producing a second set of luminance minima containing only the luminance minima exhibiting luminance drop.
