J. Kobayashi and S. Komatsu: Optical Method for Personal Identification Using Theree-Dimensinal Information of Seal Based on Logarithmic Joint Transform Correlation: Optical Experimental Results, Extended Abstracts (Optics Japan 2004) , The Optical Society of Japan, 412-413 (2004)

We propose an optical method for personal identification using three-dimensinal information of seals. Three-dimensinal information of the seal is captured as the two-dimensional projected image. The images are put through median filter and differential filter, and then they are identified by logarithmic joint transform correlation. We show the feasibilty of the proposed method by optical experiments.
