Classification accuracy versus gesture scale and translation. (a) The -axis is the scale factor, which expresses the increase of multiple of hand location in the and coordinates, applied to both the and dimensions of the test sequences. (b) The -axis is the translation factor, which expresses the pixel translation increment of hand location, applied to both the and dimensions of the test sequences.
