DWT Domain Multi-matcher On-line Signature Verification System Nakanishi, Isao 2512 ナカニシ, イサオ 80243377 Nakanishi, Isao 100000543 Sakamoto, Hiroyuki 26065 Itoh, Yoshio 4631 Itoh, Yoshio 70263481 100000466 Fukui, Yutaka 415 Fukui, Yutaka 40032023 Sakamoto, Hiroyuki 26066 This paper presents a multi-matcher on-line signature verification system which fuses the verification scores in pen-position parameter and pen-movement angle parameter at decision level. Features of pen-position and pen-movement angle are extracted by the sub-band decomposition using the Discrete Wavelet Transform (DWT). In the pen-position, high frequency sub-band signals are considered as individual features to enhance the difference between a genuine signature and its forgery. On the other hand, low frequency sub-band signals are utilized as the features for suppressing the intra-class variation in the penmovement angle. Verification is achieved by the adaptive signal processing using the extracted features. Verification scores in the pen-position and the pen-movement angle are integrated by using a weighted sum rule to make total decision. Experimental results show that fusion of pen-position and pen-movement angle can improve verification performance. conference paper IEEE 2005 AM application/pdf IEEE International Symposium on Circuits and Systems proceedings 2005 (ISCAS2005) 5413 5416 IEEE International Symposium on Circuits and Systems proceedings 2005 (ISCAS2005) AA10453415 02714302 https://repository.lib.tottori-u.ac.jp/record/7022/files/ISCAS2005_5413.pdf https://repository.lib.tottori-u.ac.jp/records/7022 eng 10.1109/ISCAS.2005.1465860 IEEE International Symposium on Circuits and Systems proceedings 2005 (ISCAS2005). 2005, 5413-5416 https://ieeexplore.ieee.org/abstract/document/1465860/ https://ieeexplore.ieee.org/abstract/document/1465860/ © 2005 IEEE.
