1. A method of a portable terminal for detecting a finger, the method comprising:
- capturing an image of a finger;
generating a likelihood image of the finger from the captured image;
localizing the finger within the likelihood image;
determining a boundary of the finger;
determining a location of one or more creases of the finger; and
comparing the determined location of the one or more creases with crease locations of a finger image stored in a database.

18. An apparatus for detecting a finger, the apparatus comprising:
-
an imaging sensor for capturing an image of a finger; and a computing system for generating a likelihood image of the finger from the captured image, for localizing the finger within the likelihood image, for determining a boundary of the finger, for determining a location of one or more creases of the finger, and for comparing the determined location of the one or more creases with crease locations of a finger image stored in a database. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
