Image resolution is progressively diminished from an initial 120 dpi resolution up to 24 dpi. The robustness of the examined system is analyzed with 2 databases and two identifiers. The first database acquires the images of the hand underneath whereas the second database acquires the images over the hand. The first classifier identifies with a multiclass support vector machine whereas the second classifier identifies with a neural network with error correction output codes. The four experiments show that an image resolution of 72 dpi offers a good trade-off between performance and image resolution for the 15 geometric features used. | URI: | http://hdl.handle.net/10553/44076 | ISBN: | 9781424441709 | ISSN: | 1071-6572 | DOI: | 10.1109/CCST.2009.5335545 | Source: | Proceedings - International Carnahan Conference on Security Technology[ISSN 1071-6572] (5335545), p. 167-171 |
