KeywordsStatistical image interpolation, orthogonality principle.
AbstractInterpolation is an image processing operation for improve the resolution of a digital image. In this work, following the orthogonality principle, and under the assumption that the actual image is a locally stationary random process, we propose an alternative scheme for image interpolation. In our approach, the computational complexity is similar to the first-order spline algorithm. The algorithm was compared with classical B-spline methods and also with a statistical interpolator previously proposed in the literature. According to the normalized mean square error criteria, the proposed method produced accurate results.
