Adaptive reconstruction method of missing textures based on kernel canonical correlation analysis

This paper presents an adaptive reconstruction method of missing textures based on kernel canonical correlation analysis (CCA). The proposed method calculates the correlation between two areas, which respectively correspond to a missing area and its neighbor area, from known parts within the target image and realizes the estimation of the missing textures. In order to obtain this correlation, the kernel CCA is applied to each set containing the same kind of textures, and the optimal result is selected for the target missing area. Specifically, a new approach monitoring errors caused in the above estimation process enables the selection of the optimal result. This approach provides a solution to the problem in traditional methods of not being able to perform adaptive reconstruction of the target textures due to the missing intensities. Experimental results show subjective and quantitative improvement of the proposed reconstruction technique over previously reported reconstruction techniques.
