A novel method is introduced to recognize and estimate the scale of time-varying human gestures. It exploits the changes in contours along spatiotemporal directions. Each contour is first parameterized as a 2D function of radius vs. cumulative contour length, and a 3D surface is composed from a sequence of such functions. In a two-phase recognition process, dynamic time warping is employed to rule out significantly different gesture models, and then mutual information (MI) is applied for… CONTINUE READING
