Layered image inpainting based on image decomposition
We propose a layered image inpainting scheme based on image decomposition. The damaged image is first decomposed into three layers: cartoon, edge, and texture. The cartoon and edge layers are repaired using an adaptive offset operator that can fill-in damaged image blocks while preserving sharpness of edges. The missing information in the texture layer is generated with a texture synthesis method. By using discrete cosine transform (DCT) in image decomposition and trading between resolution and computation complexity in texture synthesis, the processing time is kept at a reasonable level.
