摘要

旧的劣化历史文献承载着我们文化、经济等方面的重要信息，对这些文献进行适当的修复是非常必要的。这些文件经过数字化处理后，仍然存在噪声和其他低分辨率成分。这些会影响文档的整体视觉外观。本文提出了一种新的方法来增强古代历史文献。为了增强这些数字格式文档，考虑了一种双向方法。首先采用粒子群算法(PSO)和双边滤波。第二级采用双边滤波的非线性增强。然后对这两种方法进行视觉和定量测试，以显示该方法的有效性。

A novel hybrid approach to restore historical degraded documents

Old degraded historical documents carry various important information regarding our culture, economics etc. proper restoration of these documents is very necessary. After digitization of these documents there remain noises and other low resolution components. These affect the overall visual appearance of the documents. In this paper a novel approach is proposed to enhance ancient historical documents. To enhance these digital format documents a two way approach is considered. At first Particle Swarm Optimization (PSO) and bilateral filter is applied. At second level Non-Linear Enhancement with bilateral filter is applied. Both the approaches are then tested visually and quantitively to show the effectiveness of the approach.
