Factor Analysis based Print Document Identification by computer
摘要
Abstract
In order to solve the problem of print document identification when the characters in samples and test material are completely different,a new method is proposed based on factor analysis. Firstly the feature matrix is analyzed using bilinear model and the printer factor is separated from the text factor. Then the new printer feature nearly independent on text is extracted. The Bayesian decision and Expectation-Maximization algorithm are used to classify the new feature matrix. The experimental results demonstrate that this method promotes the identification accuracy significantly.关键词
