Research On The Restoration Technology Of Cultural Relics

Tibetan murals is the treasure of Chinese culture,as well as the treasures of the Chinese minorities.They also is very important to study materials,mainly used for to study the history of the Tibetan culture and Tibetan areas.This is not only our country's cultural heritage,but also the cultural heritage of the world.Therefore,the use of digital image processing techniques are used to protect the Tibetan mural painting is very important,also makes the remarkable significance to protect the Tibetan murals.In this paper,through the research analysis the features of the murals in Tibetan areas,obtained has the popularity of digital image processing technology and digital image processing technology to recover the important role of application in the mural.Second,according to the characteristics of the paintings on the walls of the Tibetan region,the research and design the process of digital image processing techniques and methods.This part of the main research contents include image acquisition in the use of advanced technology,exists in the Tibetan region and other parts of the Tibetan temple of murals,paintings on the walls of the collected digital processing,such as the high frequency part of image denoising,digitized image restoration of the original murals,simplifying the image restoration processing,mural color image processing,through the gray degradation model and other technical methods;Due to the original frescoes supported wall damage in the form of main wall cracks or falls off the wall,so edge detection technology is used to identify the boundary of the damaged area,according to the characteristics of the fictitious image based on the structure and texture information,on the basis of image restoration are analyzed and the algorithm of texture image,the algorithm combining with the structural image and texture image restoration algorithm,based on the advantages of image block recovery algorithm,also restricts the sample image restoration algorithm of block model.Through research,this paper not only summarizes the image restoration technology and image reconstruction technology,and it also introduce several kinds of image restoration technology and image reconstruction methods.Through MATLAB experiment plan won the treatment effect of the actual display.
