Abstract

The invention discloses a portrait stone crack intelligence extraction and virtual restoration method. The method comprises the following steps of 1) acquiring a digital image of a portrait stone and preprocessing the digital image of the portrait stone; 2) for the preprocessed digital image of the portrait stone, using a crack extraction algorithm based on an editing distance to carry out crack disease calibration so as to acquire a mask image, and then acquiring a labeled graph of a crack disease in the portrait stone according to the mask image; 3) using a Criminisi restoration algorithm based on a MRF matching criterion to carry out digital restoration on the digital image of the portrait stone according to the labeled graph of the crack disease in the portrait stone which is acquired from the step 2), generating the restored digital image of the portrait stone and then displaying the restored digital image of the portrait stone. The method can be used to satisfy the restoration of the digital image of the portrait stone.

Description

technical field

[0001] The invention belongs to the field of digital image processing, and relates to an intelligent extraction and virtual restoration method of cracks in portrait stones. Background technique

[0002] Pictorial stones are a kind of ancient murals, and they are mainly architectural stones for carving portraits on buildings such as catacombs, cemetery ancestral halls, tombs and temples in the Han Dynasty. They are not only the carrier for researching and inheriting and carrying forward the traditional stone carving art of our country, but also precious materials for the research of history, politics, military affairs and art. Different from paper documents, portrait stone documents are solitary and will not be regenerated once damaged. However, currently insufficient attention is paid to portrait stone documents. In addition, the complexity of the natural environment around the portrait stone, the immaturity of scientific and technological protection methods,...
