Abstract
An appearance­based framework for 3D hand shape
classification and simultaneous camera viewpoint estima­
tion is presented. Given an input image of a segmented
hand, the most similar matches from a large database of
synthetic hand images are retrieved. The ground truth la­
bels of those matches, containing hand shape and camera
viewpoint information, are returned by the system as esti­
mates for the input image. Database retrieval is done hi­
erarchically, by first quickly rejecting the vast majority of
all database views, and then ranking the remaining can­
didates in order of similarity to the input. Four different
