Abstract(in English) This paper proposes a reconstruction method of missing textures in still images using an ER(Error Reduction) algorithm which is one of phase retrieval methods. The proposed method defines constraints used in this algorithm in such a way that the target local image and its Fourier transform magnitude are respectively in two subspaces generated from some clipped local images and their Fourier transform magnitudes. Then, the Fourier transform magnitude and phase of the target local image are estimated so that the missing area can be reconstructed. Further, the proposed method adaptively selects the local images and Fourier transform magnitudes utilized to generate these subspaces for the target local image. Consequently, the proposed method can accurately reconstruct the missing textures by utilizing the ER algorithm including the novel constraints. Some experimental results are shown to verify the high performance of the proposed method.
