Method of signature recognition with the use of the mean differences

The paper presents a new method of recognizing handwritten signatures, based on the mean differences, which has been modified appropriately. The modification proposed by the authors consists in dividing signatures into windows and calculating similarity values between individual windows. Each signature is represented as a set of features with specific values. Coordinates of signature points, pen pressure, and speed of writing have been accepted as signature features. The influence of the size of windows and their position in a signature have been analysed within the study. Additionally, the influence of individual features on the signature similarity value has been examined.
