基于Criminisi算法的四经绞罗纹样修复研究OACSTPCD

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 modem 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 modem 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 camed 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.
