Embodiment

[0091] This embodiment of the intelligent terminal system for the digital restoration of nail-on-nail disease in ancient murals is completed on the Android platform.

[0092] The use of the intelligent terminal system for the digital restoration of the ancient murals from nail damage is as follows:

[0093] Log in to the module after turning on the system. This module requires the user to fill in the registered account number and password, verify and complete the login. If you are a new user, you need to jump to the registration module from this interface, first complete the registration of user information, and then go to the user login module.

[0094] After logging in, enter the mural image library interface. On this interface, you can see the mural images stored in the gallery, and select the murals you are interested in for restoration research. At the same time, the module also has functions such as scanning codes, taking pictures, and querying knowledge bases.

Abstract

The invention discloses a digital restoration method for flaking diseases of ancient wall paintings based on compressed sensing, and an intelligent terminal system. The method employs a wall painting image preprocessing module, a wall painting flaking disease marking module and a wall painting image restoration module. The method comprises the steps: enabling the wall painting image preprocessing module to carry out the image denoising and HSV color space transformation, enabling the wall painting flaking disease marking module to achieve the V component extraction of a wall painting image, drawing a brightness contour map through a contour function, carrying out the threshold segmentation of the brightness contour map, and obtaining wall painting segmented images; obtaining a closed interval of a disease region through the morphological corrosion operation, carrying out the overlapping of the segmented images and a damaged wall painting image, and marking the flaking disease region of the wall painting; enabling the wall painting image restoration module to carry out the restoration of the flaking disease region of the wall painting through an image restoration algorithm based on compressed sensing of a PMLE mechanism and an EM mechanism. The method can independently complete the marking of the flaking disease region in the ancient wall painting and the intelligent restoration, and provides support for the digital virtual display of the wall painting.

Description

technical field [0001] The invention belongs to the field of digital image processing, and in particular relates to a method for digitally repairing nail-on-nail diseases of ancient murals based on compressed sensing and an intelligent terminal system. Background technique [0002] As a country with a large number of cultural relics, our country has always been a difficult problem to solve in terms of cultural relics preservation, research, and restoration. Many cultural relics cannot be displayed because they cannot be repaired in time, and even eventually damaged. With the rapid development of computer image processing technology, digital image restoration technology is widely used in the field of cultural relics restoration and protection. [0003] The idea of ​​digital image restoration technology is to infer the unknown information of the damaged area according to the known information of the intact area in the image, so as to achieve the purpose of restoration. The co...
