Through calculating the connected components of the background area of character image,hole features of a handwritten character image can be extracted.

A new way for handwritten character recognition is proposed in the paper.

To overcome handwritten character pattern s instability caused by different writing styles, a novel approach is proposed in this paper.

Study of electronic handwriting signature verification arithmetic;

The foundation and the structure of the model to deal with the random and non maturity problems of handwriting signature samples were discussed.

A sequence of the feature of handwriting signature is equally divided into segments, and weight factors decided by stability degrees of each segment are considered in the correlation coefficients computing.

Recognition algorithm of online handwritten signature;

Not content to method of feature selection applied in the field of handwritten signature,the theory of support vector machine applied in the algorithm which better applied in high-dimension data avoid the question of dimension-destroy in the feature selection.

The electronic handwritten signature verification technology includes a signature gathering system,and a signature verification system.
