| Abstract: | Authentication system solely based on visual lip information is of advantage since the uttering characteristic/manner is unique to individual. This paper presents the results of studying for the most appropriate features extracted from the lip motion for person authentication application. The geometric-based, shape-based and inner lip features are derived from a 14-point Active Shape Model (ASM) lip model. The dynamic features reflecting the differential changes of the feature parameters are also considered in the experiment. A database consists of 40 speakers and each of their utterance last for 3 second. Various combinations of features obtained by analyzing this database are fed into a Hidden Markov Model (HMM) classifier for processing. It is observed that the best result has been obtained when both shape-based features and inner lip features are used. | ||
