| Abstract | This paper presents a new framework that models facial expressions in multiple people with different expressions and synthesize new stylized subtle facial expressions using the generative models. As facial expressions pass through nonlinear shape deformations during facial expressions, we model the facial expression in nonlinear mapping space based on low dimensional embedding and kernel mapping. Characteristics of different type of expressions and variances in different people are decomposed by analyzing the nonlinear mapping between the Euclidean space of facial motion and a low dimensional embedding of these expressions. Using high resolution tracking of densely sampled 3D data, the generative model can control subtle facial expression characteristics of different person in different expression by low dimensional person dependent style factor and expression type dependent expression factor. The temporal characteristics of the motion can also be controlled by the trajectory sampling on the low dimensional embedding manifold which is independent of person style and expression type. Our experimental results are shown for subtle differences in different smile expressions in different people from dense 3D tracking. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
