Toward an Efficient Body Expression Recognition Based on the Synthesis of a Neutral Movement

Abstract : We present a novel framework for the recognition of body expressions using human postures. Proposed system is based on analyzing the spectral difference between an expressive and a neutral animation. Second problem that has been addressed in this paper is formalization of neutral animation. Formalization of neutral animation has not been tackled before and it can be very useful for the domain of synthesis of animation, recognition of expressions, etc. In this article, we proposed a cost function to synthesize a neutral motion from expressive motion. The cost function formalizes a neutral motion by computing the distance and by combining it with acceleration of each body joints during a motion. We have evaluated our approach on several databases with heterogeneous movements and body expressions. Our body expression recognition results exceeds state of the art on evaluated databases.
