A three-mode expressive feature model of action effort
James W. Davis, Hui Gao, Vignesh S. Kannappan · 2003
We present an expressive feature model for recognizing the performance effort of human actions. A set of low and high effort examples for an action are initially factored into its three-mode principal components, followed by a learning phase to compute the expressive features required to bring the model estimation of effort into agreement with perceptual judgements. The approach is demonstrated using real and illusory movements.
