J. Kobayashi and S. Komatsu: Identification of Seals Based on Joint Transform Correlation: Exploiting 3-D Information, Extended Abstracts (Optics Japan 2002) , The Optical Society of Japan, 260-261 (2002)

We propose a method for identifying seals based on joint transform correlation (JCT), which exploits the 3-D information on their surface profile. In order to confirm the feasibility of the method, we examined the dependence of the JTC output value on both the different names and the depth of the surface profile carved on the seal's head.
