Abstract

The invention provides a mural image color restoration method, device, storage medium and computer equipment. The method includes acquiring the mural image to be restored and the reference mural image; extracting the color features of the mural image to be restored and the reference mural image; The color characteristics of the image and the reference mural image are constrained by the maximum mean difference, and the mural image to be restored is subjected to global color restoration to generate the first color restoration image; through the Markov random field constraint, local color restoration is performed on the first color restoration image, Generate a second color restoration image; minimize the Euclidean distance between the second color restoration image and the mural image to be restored to obtain a third color restoration image; perform noise suppression processing on the third color restoration image. The application can effectively maintain the original structural information in the mural image, and has a good overall restoration effect on faded and discolored areas, and improves the color restoration effect of grotto murals.

Description

technical field [0001] The present invention relates to the field of mural painting restoration, in particular to a mural image color restoration method, device, storage medium and computer equipment. Background technique [0002] Grotto murals are paintings drawn by the ancients on the walls of caves. They are one of the greatest and most glorious historical and cultural heritages of mankind. Through these murals, one can fully understand ancient Buddhist thoughts and valuable information and historical clues in multidisciplinary fields such as Chinese traditional culture, history, geography, and humanities. [0003] For a long time, due to the influence of factors such as the environment, the manufacturing materials of murals, and the mineral composition of the grotto walls to which murals are attached, a large number of existing mural images have experienced degradation and qualitative changes. Among them, the more serious and difficult problem is the fading and discolor...
