Abstract

To address the problems such as background noise and uneven illumination during the extraction of ancient ceramic patterns. A nondestructive extraction method for missing patterns in ancient ceramics is proposed. Combined with the characteristics of the pattern, the median filter matrix equation is designed to denoise the image. By defining the median filter equation function for the high-frequency approximation coefficient of the wavelet transform, the details of the ancient ceramic pattern are clearer. The double histogram equalization algorithm is built to maintain the average brightness of the image, which is helpful to the extraction and analysis. The verification shows that the method can effectively eliminate the interference of noise on the extraction of the ancient ceramic pattern, and the accuracy of the segmentation reaches 94%. It effectively promotes the restoration and protection of ancient ceramic cultural relics.

古陶瓷纹理特征的完整提取方法研究
针对古陶瓷图案提取过程中存在的背景噪声和光照不均匀等问题。提出了一种无损提取古陶瓷中缺失图案的方法。结合图案的特点,设计中值滤波矩阵方程对图像进行去噪。通过定义小波变换高频近似系数的中值滤波方程函数,使古陶瓷图案的细节更加清晰。为了保持图像的平均亮度,建立了双直方图均衡化算法,有利于图像的提取和分析。验证表明,该方法能有效消除噪声对古陶瓷图案提取的干扰,分割正确率达到94%。它有效地促进了古代陶瓷文物的修复和保护。
