摘要
This study uses an extracting technique to obtain palm images. The algorithm proposed in this study can determine the precise locations of fingertips and finger-to-finger-valleys on a hand. After locating these positions, palm images can be extracted. Such images contain many useful geometrical features, which can be used to identify palms. The orientations and centroids of palms arc identified in this study. Image rotation, shifting, and interpolation techniques are used to align different palms to the same position for geometrical comparison. (C) 2007 Elsevier Ltd. All rights reserved.
