Improved exemplar-based inpainting algorithm for broken Thangka images
Weilan Wang · Journal of Computer Applications · 2010
The algorithm of exemplar-based image inpainting was introduced to the digital protection of Thangka image due to the advantage that can repair the broken structure and texture effectively at the same time.This algorithm is good at repairing the specific broken images of Thangka,but is not appropriate to other kinds of broken images.Hence,this paper proposed two aspects of improvement for the deficiencies of exemplar-based broken Thangka image inpainting:the improvement of computing method of confidence and the improvement of computing method of isophote intensity.The problem that optimum exemplar block is not exclusive has been solved.The experimental results show that the improved algorithm can not only get a satisfied inpainting result but also improve repairing efficiency.
