| Zusammenfassung: | A method and system for detecting the concha and intertragal notch in an undetailed 3D ear impression is disclosed. The concha is detected by searching vertical scan lines in a region surrounding the aperture using a two-pass method. The intertragal notch is detected based on a bottom contour of the 3D undetailed ear impression and a local coordinate system defined for the 3D undetailed ear impression. |
