Abstract

In this paper, we propose a new manifold representation for visual speech recognition. The developed system consists of three main steps: a. Lip extraction from input video data. b. Generate the Expectation-Maximization PCA (EMPCA) manifolds for the entire image sequence and perform manifold interpolation and re-sampling. c. Classify the manifolds using a HMM classifier to identify the words described by the lips motions in the input video sequence.
