ABSTRACT:
The classical TV (Total Variation)
model has been applied to gray texture image denoising and inpainting previously
based on the non local operators, but such model can not be directly used to
color texture image inpainting due to coupling of different image layers in
color images. In order to solve the inpainting problem for color texture images
effectively, we
propose a non local CTV (Color Total Variation) model. Technically, the
proposed model is an extension of local TV model for gray images but we take
account of the coupling of different layers in color images and make use of
concepts of the non-local operators. As the coupling of different layers for
color images in the proposed model will in-crease computational complexity, we also
design a fast Split Bregman algorithm. Finally, some numerical experiments are conducted
to validate the performance of the proposed model and its algorithm.
