%X Palm line structure features are clear and stable, and they can uniquely describe a palmprint. Because the directions of palm lines are arbitrary and irregular, it is very difficult to accurately represent their structure features with an expression. This paper presents a new approach to line structure features representation and matching for palmprint recognition. It uses improved water-filling algorithm to extract the statistical structure features and direction structure features and label palm lines direction information from the extracted palm lines image. Finally, the extracted global statistical structure features and local detail direction structure features are combined as a feature vector, which is used in the next recognition. The experimental results show the method not only has a good property in matching, but also it can get a better accuracy.
