In this paper, we introduce simply partitioned DP (dynamic programming) matching and threshold equalizing into the verification process in DWT (discrete wavelet transform) domain on-line signature verification in order to improve the performance. The simply partitioned DP matching divides both data series (verification and template data) into several partitions and calculate sub DP distance every partition. Even if mismatched pairs are caused in each partition, they are initialized at thedoi:10.1109/icfhr.2010.22 dblp:conf/icfhr/NakanishiNK10 fatcat:7466zehjizenrjj7f3gngydrkm
