通过古陶瓷表面的纹饰特征来对古陶瓷器具进行断源断代是我国古陶瓷鉴定领域的传统方法之一。使用Matlab软件对古陶瓷纹饰进行数字化处理,可以发掘出更多古陶瓷纹饰所蕴含的深层次的数字信息,有助于提高古陶瓷鉴定精度。在对古陶瓷纹饰进行数字化的过程中,边缘提取的算子选择决定了图片的清晰度。本文采用不同算子对古陶瓷样品的纹饰进行边缘提取处理,对比其处理效果,研究发现Sobel算子可作为古陶瓷纹饰边缘提取的最优算子,为我们后续利用数字化技术对古陶瓷的纹饰特征进行研究和探索打下了坚实的基础。
It is one of the traditional methods in the field of ancient porcelain identification in China that the ancient ceramic ware is broken through the decorative features of the ancient ceramic surface. The use of Matlab software to digitize the ancient ceramic ornamentation can reveal more deep digital information contained in the ancient ceramic ornamentation and help to improve the identification accuracy of ancient ceramics. In the process of digitizing ancient ceramic ornamentation, the choice of operator for edge extraction determines the sharpness of the picture. In this paper, different operators are used to carry out the edge extraction of ancient ceramic samples. Compared with the treatment results, it is found that the Sobel operator can be used as the optimal operator to extract the edge of the ancient ceramic decoration. Characteristics of research and exploration laid a solid foundation.
