Abstract
Natural textures with gradually changed illumination bring great troubles to the field of image inpainting. Using the improved dynamical modeling approach, an energy function model gradually changed from the center to the boundary of data missing region of image is established. On this basis, a gradually changed directional priority function is proposed to ensure the gradual propagation of texture synthesis. In addition, to achieve the feasible propagation of the boundary between different textural regions, the relative test point selection, as well as energy function modeling approach, is also discussed for different cases. Besides, the established energy function models are theoretically evaluated to demonstrate their accuracy in images. Experimental results show the effectiveness of the proposed approach in the natural images with gradually changed illumination.
