基于不变矩的书法真伪鉴定方法研究

The Authenticity Identiffcation Method of Calligraphy Based on Image Shape Fidelity

传统的书法真伪鉴定多采用专家鉴定等方式,基于图像形状真实度提出了一种书法真伪鉴定方法,将模式识别领域中的不变矩应用于书法真伪鉴定,分析比较了Hu矩、Zernike矩、Pseudo-Zernike矩、Legendre矩、Fourier-Mellin矩、Tchebichef矩和Krawtchouk矩等七种不变矩的形状真实度性能,并提出了衡量书法作品形状真实度的评价指标。通过高清晰、高精度、高保真的书法作品图像的采集与处理,进一步保证了鉴定的可靠性。实验结果表明,该方法能识别出肉眼不易观察的差异,可为书法鉴定提供一种科学可靠的辅助手段,提升了书法作品鉴定的效率与可信性,鉴定时间开销小且抗干扰性好,在书法真伪鉴定中具有一定借鉴意义及较好的实用价值。

The traditional authenticity identification of calligraphy is usually applied in the manner of expert appraisal or spectral analysis.A new authenticity identification method of calligraphy which is based on image shape fidelity is proposed in this paper.The invariant moment applying to the field of pattern recognition is used for the authenticity identification of calligraphy.Seven invariant moments are tested for the performance of shape fidelity,including Hu moment,Zernike moment,Pseudo-Zernike moment,Legendre moment,Fourier-Mellin moment,Tchebichef moment and Krawtchouk moment.The concept of shape fidelity is proposed as the assessment index of the authenticity of calligraphy.The reliability of identification is further guaranteed by the high definition,high precision and high fidelity image acquisition and processing of calligraphies.Experimental results show that our method can recognize the differences in calligraphies which are difficult to distinguish with the naked eyes and can improve the efficiency and credibility of the identification of calligraphies with low cost of identification time and better anti-interference.It has a good significance in the authenticity identification of calligraphy.
