Recognition of facial action units (AU) is one of two main streams in the facial expressions analysis. Action units deform facial appearance simultaneously in landmark locations and local texture as well as geometry on 3D faces. Thus, it is necessary to extract features from multiple facial modalities to characterize these deformations comprehensively. In order to fuse the contribution of the discriminative...
Automatic facial expression recognition on 3D face data is still a challenging problem. In this paper we propose a novel approach to perform expression recognition automatically and flexibly by combining a Bayesian Belief Net (BBN) and Statistical facial feature models (SFAM). A novel BBN is designed for the specific problem with our proposed parameter computing method. By learning global variations...
Image classification plays an important role in many tasks, which is still a challenging problem. This paper proposes a hybrid image classification method, which integrates wavelet transform, rough set approach, and artificial neural networks (ANNs). Wavelet transform is employed to decompose the original images into different frequency sub-bands, then a set of statistical features are extracted from...
