Nearest Neighbor Value Interpolation

Author 1: Olivier Rukundo Author 2: Hanqiang Cao

This paper presents the nearest neighbor value (NNV) algorithm for high resolution (H.R.) image interpolation. The difference between the proposed algorithm and conventional nearest neighbor algorithm is that the concept applied, to estimate the missing pixel value, is guided by the nearest value rather than the distance. In other words… Read full abstract & cite →
