| Abstract: | Against the disadvantages of classic DTW low speed on verification, proposes an online handwritten signature verification algorithm based on DTW using special data points.The special data points can contain a number of information about signature characteristics, and these information may reveal basic characteristics of the signatory.This algorithm rapidly shortens verification time while the target of verification is similar to that of classic DTW using the whole data points.The result of experiment proves... |
