| Outline of Final Research Achievements |
In forensics, criminals can be identified by ear shape alone. However, the shooting angles of a suspect in images taken by surveillance cameras and those in mug-shots taken of the same suspect are not necessarily the same. Hence, differences due to shooting angle must be taken into consideration, because ear shape is not planar. In a previous report, we proposed a method for single-view based ear biometrics that accounted for the rotation in depth. This method uses discriminant analysis for the estimated Gabor features for different poses. (Watabe, et al., ITEJ, 65(7), 1016-1023, 2011). By refining this method, we have developed a practical system supporting crime investigators in identifying suspect candidates from ear images taken at various shooting angles in surveillance videos. In the following, various improvements in the robustness and the applicability of the present method are described.
