Image-based facial expression recognition
… Soft Vector Quantization and Supervised Hierarchical Gaussianization algorithms. The key idea in both of these is to iteratively update the Gaussian Mixture Models in such a way that they are more suitable for classification in these respective frameworks. We then present some exciting …

Joint appearance and locality image representation by Gaussianization
… the image level and image patch level, in a hierarchical Bayesian framework using mixtures of Gaussians. After such a hierarchical Gaussianization, each image is represented as a Gaussian mixture model (GMM) for its appearance, and several Gaussian maps for its spatial layout. Then we extract …
