Color Image Completion Using Simultaneous Geometry and Texture

In this paper, a hybrid inpainting method is proposed for the simultaneous reconstruction of geometry and texture in missing regions of a color image. Using inpainting methods based on partial differential equation (PDE) to fill in large image regions usually fails if these regions contain textures. On the other hand, texture synthesis algorithms sometimes fail due to complex structure and texture in a given image. However, this study suggesting a hybrid method that consists of both techniques generates satisfactory results in completing the missing parts. In the proposed method, the given image is decomposed into two components. The geometry component is inpainted by the tensor-driven PDE algorithm which takes curvatures of line integral curves into account and the texture component is reconstructed by the modified exemplar-based inpainting algorithm. Both of these methods work based on color information. Experimental results show that the proposed method efficiently completes missing regions.
