Confidence Fuzzy Interval in Verification of Offline Handwriting Signature
A new approach in verification of offline handwriting signature had been proposed. This approach use confidence fuzzy interval for verification. This confidence fuzzy interval achieved by using alpha-cut of triangular fuzzy number where the value of alpha-cut will reduce the interval of confidence fuzzy interval. The best confidence fuzzy interval consists less number of signature from the present number of the signature determined by the best value of alpha-cut. Then, defuzzification method used to achieve defuzzification signature. The signatures modeled by piecewise fuzzy interpolation rational cubic Bezier curve.
