基于Criminisi算法的四经绞罗纹样修复研究

Research on pattern restoration of four-warp twisted Luo based on the Criminisi algorithm

文章针对古代罗织物受到诸多因素影响而产生破损、难以提取修复这一问题,提出了一种结合开运算和Criminisi算法的图像修复方法。收集具有规律性特征的四经绞罗传统纹样,用图谱分析法分析最具代表性的菱形纹,使用原算法和开运算改进过的Criminisi算法,对图像进行剪裁,得出掩膜,计算优先权后进行纹样填充,完成了四经绞罗规律型图样的数字化修复。结果表明,经过开运算改进的Criminisi算法弥补了原算法的不足,修复后的图像和原算法修复的相比更加清晰平滑,验证了此算法修复四经绞罗纹样的可行性与可信性,为罗织物的传承和修复提供了较为可靠的方法。

The traditional culture of China has been widely concerned and highly valued by people,so more and more designers have begun to actively explore and apply excellent local traditional cultural resources.However,in the face of a large number of cultural relics that need to be repaired,reuse becomes a problem.When cultural relics cannot be repaired,their pattern characteristics cannot be reused.The ancient warp twisted fabrics in China are unique and distinctive in style.In the long history of development,the warp twisted fabrics have developed diverse organizational structures and experienced several major changes and transformations.Taking Luo as the representative,the development of its organizational structure is closely related to the social development and technological evolution under the historical environment at that time.Because it is difficult to weave,it is damaged and difficult to extract due to many factors,and the diversified warp twisted weaving techniques in ancient times have only been inherited in a small part in modern times.Therefore,whether for the technical and social humanistic connotation carried by the ancient warp twisted fabric itself,or the inheritance and development of its skills in modern times,there is still a lot of room for research.To solve the problem that ancient Luo fabrics are damaged and difficult to extract and repair due to many factors,an image restoration method combining open operation and Criminisi algorithm is proposed.The theoretical research and practical application of the four-warp twisted Luo are hindered by the complicated weaving method,long construction period,and few cultural relics and few reference objects.At present,in the aspect of preserving and studying the four-warp twisted Luo,the pattern is still woven by hand,which is not conducive to the development and spread of the four-warp twisted Luo.Compared with the traditional manual restoration,the digital pattern restoration technology has been widely concerned in the field of cultural relics pattern restoration,and it has the advantages of higher efficiency,lower cost,high flexibility and easy adjustment of repair results,becoming the focus and frontier of current research.It provides diversified means and ideas for the restoration and extraction of four-warp twisted Luo.According to the historical origin and classification of warp-twisted fabrics,the most representative four-warp twisted Luo was obtained,the weaving technology and inheritance characteristics of the four-warp twisted Luo in the historical development process were discussed,the unique weaving techniques of the four-warp twisted Luo were summarized,and the types and characteristics of the four-warp twisted Luo patterns were summarized.The traditional patterns of four-warp twisted Luo with regular features were collected,and the most representative diamond patterns were analyzed by atlas analysis.By using the original algorithm and Criminisi algorithm improved by open operation,a series of operations were carried out on the images,which made the priority selection of the areas to be repaired more accurate,mainly including image clipping,obtaining the mask,calculating the priority,and finally filling the patterns to complete the digital restoration of the four-warp twisted Luo regular patterns respectively.Two groups of repair models were obtained and compared.The experimental results show that the improved Criminisi algorithm makes up for the shortcomings of the original algorithm,and the restored image is clearer and smoother than the original algorithm,which verifies the feasibility and credibility of this algorithm to repair the four-warp twisted Luo pattern,and provides a more advanced method for the inheritance and repair of Luo fabrics.This study aims to realize the inheritance of the representative pattern characteristics of four-warp twisted Luo,and provide new ideas for the inheritance and development of Luo fabrics.Analyzing the present situation of the application of traditional cultural elements in modern society with existing design examples,this paper puts forward feasible innovative methods of four-warp twisted Luo patterns in modern design,and summarizes the basic principles of the application of four-warp twisted Luo design elements.And the previous research on its aesthetic characteristics and cultural connotation is integrated,in order to realize the inheritance of the representative pattern characteristics of the four-warp twisted Luo,and provide new ideas for the inheritance and innovation of traditional cultural elements.
