Tujia brocade traditional residual pattern digital repair method

Abstract

The application discloses a Tujia brocade traditional residual pattern digital repair method, comprising damaged area automatic detection, image structure component and texture component decomposition, structure component variation PDE repair and texture component texture synthesis repair, and concretely comprising the steps of: building a Tujia brocade digital image damaged area automatic detection and positioning model; constructing a variation image decomposition mode to decompose a Tujia brocade image into a structure component and a texture component; designing a variation PDE mode to repair the Tujia brocade structure component, and a texture synthesis algorithm based on samples to repair the Tujia brocade texture component; and finally, synthesizing the structure component and texture component after repair to obtain the complete repair of the Tujia brocade digital image. The Tujia brocade traditional residual pattern digital repair method repairs a Tujia brocade traditional residual pattern through the digital technology, can find the most satisfactory repairing effect through multiple tries, meanwhile does not need to damage original brocade, and provides a safe and convenient approach for Tujia brocade repair work.

Description

technical field [0001] The application belongs to the field of digital image restoration, and in particular relates to a method for digital restoration of traditional Tujia brocade patterns. Background technique [0002] Tujia brocade is a wonderful flower of Tujia national craft, known as the "Flower of Tujia". Tujia brocade weaving has a long history, and the Tujia brocade weaving was first recorded in "Book of the Later Han Dynasty: Biography of the Southwest Barbarians". In its generation, development and changes, Tujia brocade fully embodies the perfect combination of practicality and artistry, and has become an important carrier for inheriting Tujia culture and art. In June 2006, Tujia brocade was listed in the first batch of national intangible cultural heritage protection list. [0003] However, with the acceleration of the modernization process, the protection and inheritance of Tujia brocade is also facing severe challenges due to the influence of various factors...

AI Technical Summary

Problems solved by technology

However, the restoration at that time was mainly carried out manually by art restoration experts relying on professional knowledge. This restoration method has the following disadvantages: (1) the restoration efficiency is extremely low; (2) the original precious artwork may be destroyed

However, the current research results in this area are still relatively few, and a small amount of research is also focused on the improvement of theoretical models and algorithms, and few use this technology to carry out targeted research on certain digital images.

[0009] To sum up, at present, a certain amount of research work has been carried out on image restoration at home and abroad, but there are few restoration studies based on variational decomposition, and the research on digital restoration of Tujia brocade is basically blank.
