DCT Inpainting with Patch Shifting Scheme
This paper presents a novel exemplar-based image inpainting whose patch matching process is done in frequency domain in order to gain the advantage of noise reduction property. Moreover, a simple patch shifting scheme is also introduced to make sure that the target patch contains enough information to refer the unknown region. Each target patch is iteratively shifted to the position where there are enough known pixels on the patch as defined by user. This scheme can improve the traditional exemplar-based inpainting techniques which do not consider on the number of known and unknown pixels in the target patch. This ignorance can ruin the inpainting result when few known pixels are in the target patch. More meaningful target patches are provided by the proposed scheme. Experimental results show a significant improvement from traditional exemplar-based approach in both visual and mathematical aspects. Sharper and more continuous edge can be achieved by our approach.
