为解决现有打印文件鉴别方法需要相同字符匹配的条件限制，提出了一种基于纹理合成的打印文件鉴别方法。通过对已知纹理样本块的操作，将字符图像中的空白部分修复，得到完整的纹理图像，从而消除字符内容的干扰。在打印文件鉴别实验中，通过提取完整纹理图像的灰度共生矩阵特征，并对两份打印文件的特征距离进行分类判别，最后取得了98％的正确率。

The current printed document identification methods are limited by the condition of requiring the same character to compare.In order to address this problem, a printed document identification method based on texture synthesis is proposed.The blank parts of the character image are filled through copying the sample block of the know texture.Thus a complete texture image which is not affected by the content of character is obtained.Through extracting the gray level co-occurrence matrix ( GLCM) feature of the complete texture images and calcu-lating the feature distance of two documents, the recognition rate is 98%in the printed document identification ex-periment.
