Abstract
In this paper, we propose fast hybrid interpolation methods that employ more than one interpolation algorithm and choose the most appropriate interpolation algorithm that provides high quality images with a minimum processing time. In the proposed algorithm, we first apply a test to predict which interpolation is most appropriate for a given pixel in terms of complexity and performance. Then, a simple interpolation algorithm is used for pixels for which the simple interpolation algorithm provides acceptable performances and a complex interpolation algorithm is used for pixels for which the complex interpolation algorithm significantly outperforms the simple interpolation algorithm. Consequently, it is possible to obtain high quality images without significantly increasing the processing time.
