| Abstract | In this paper, the effects of dynamic facial expression properties on the recognition of emotions were investigated. Although many studies of facial expression recognition and analysis have been conducted, the stimuli used in these experiments were typically static. Even when dynamic facial expressions were used, the experimental task was restricted to the basic expressions. In natural communication environments, facial expressions are often subtle or ambiguous. Studies of the analysis and synthesis of subtle and dynamic facial expressions are therefore required. As a quick going up expression could be recognized as a different emotion from a slow rising one, we represented facial expressions as the combination of time function of intensity and presentation speed. Experiments using stimuli that were combinations of four intensity time functions and three presentation speeds were conducted. Participants rated the perceived intensity of the emotions depicted, as well as how realistic they appeared to be. Time function and speed had different effects on different emotions, i.e. perceptions of anger were affected by set up speed, and the perceived intensity and realism of smiling expressions were also affected by speed. |

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.
