Application of the Feature of Lip Motion in Continuous Image to Personal Identification

Abstract

The aim of this paper is to apply the feature of lip motion in continuous image to personal identification. At first, four feature points are selected around the lip region. Next, the following are respectively computed: distance between the upper and lower and distance between the right and left. Finally, personal identification is carried out using the features that made by the measurements in continuous image.
By using the Mahalanobis distance, twenty persons are accurately distinguished. The experimental result indicates the effectiveness of the feature of lip motion to personal identification.
