In this paper, we present a novel approach to address the problem of eye shape characterization via curve representation. Firstly, a directional triangle-area curve representation method (DTAR) is presented for this aim. Equipped with DTAR, the shape similarities between two eyes can be measured by the similarities between two corresponding DTAR curves. Secondly, in order to exploit the underlying information of eye shapes, a curve clustering algorithm is utilized to automatically discover a set of eye shape prototypes. Consequently, a semantics extraction method for eye shapes is proposed in terms of seven reference eye shapes. Finally, in order to validate the consistency of the clustering results and the extracted semantics, extensive experiments on AR and BU4DFE databases are designed and conducted, and all the results demonstrate the effectiveness of the proposed DTAR curve representation and the semantics extraction method.
