We propose a new method for estimation of area of mouth opening from a video sequence of the speaking person. In a paper published in 2000, Grant and Seitz have reported the different degrees of correlation between acoustic envelopes and visible movements. In our method, we exploit these correlations to establish a mathematical model of a Single-Input Multiple-Output (SIMO) system in which the area of mouth opening is the unknown Single Input that we need to estimate. The subband Root Mean… CONTINUE READING
