This invention proposes a method and system for Thangka image restoration, relating to the field of image restoration. The method includes: preprocessing the acquired original Thangka images; classifying the preprocessed images into first, second, third, and fourth Thangka images according to their complexity from low to high; sequentially performing damage processing on these Thangka images to form structurally damaged, textured, semantically abnormal, and mixed-damaged images; training these damaged images to form a Thangka restoration model; and using the Thangka restoration model to restore the Thangka image to be restored, forming the target restored image. This invention combines the classification and damage processing of different Thangka image complexities to obtain different types of damaged images, adapting to different damage scenarios. Furthermore, by training and optimizing different damaged images separately, the resulting Thangka restoration model can comprehensively restore Thangka images, ensuring that the restored image has a regular structure, natural texture, reasonable semantics, and high fidelity.

This invention relates to the field of harmless treatment technology for oily sludge, specifically to a method for preparing carbon quantum dots from oily sludge. Conventional methods for preparing carbon quantum dots from oily sludge have limitations in yield and fluorescence intensity. To address these issues, this invention provides a method for preparing carbon quantum dots from oily sludge. Considering the complex composition of oily sludge, this invention designs a multi-stage purification process chain of "ultrasonic extraction—water washing—Soxhlet extraction—acidification treatment." Each step works synergistically, purifying the sludge step by step to ultimately obtain a high-purity refined organic carbon source. The refined organic carbon source removes impurities through gentle solvent extraction and acid washing, maximizing the preservation of the organic carbon source's chemical activity and structural integrity. In the hydrothermal reaction, it can be effectively converted into carbon quantum dots, avoiding carbon source loss or activity reduction due to over-processing, thus further improving the yield and fluorescence intensity of carbon quantum dots.
