Discrete Cosine Transform based Image Inpainting

This paper proposes a novel scheme for image inpainting based on discrete cosine transform (DCT). The DCT as an orthogonal transform is used in various applications. In this view the rows of a DCT matrix as the filters associated with a multiresolution analysis. In this paper, propose to utilize the noise reduction property of cosine transforms for image inpainting. Current methods may available using time domain analysis by direct spatial image inpainting techniques and those that perform frequency domain analysis by indirect frequency image inpainting techniques. However, both have their own advantages and limitations. This method used for removing noise, filling missing information over regions with sensible sizes, visual quality of image with frequency domain analyses.
