Abstract
Hybrid interpolation methods are provided that employ more than one interpolation algorithm and choose the most appropriate interpolation algorithm that provides high quality images with a minimum processing time. Prediction means is first applied 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, which requires a larger number of operations, significantly outperforms the simple interpolation algorithm. Consequently, it is possible to obtain high quality images without significantly increasing the processing time.
Claims3
A hybrid interpolation method comprising:
- a simple interpolation algorithm;
- a complex interpolation algorithm that requires a larger number of operations but provides a better performance than said simple interpolation algorithm;
- prediction means that predicts an appropriate interpolation algorithm, which provides a high quality image with a minimum processing time, for a new pixel to be interpolated;
- and
- performing means that chooses either said simple interpolation or said complex interpolation according to said prediction means and performs interpolation for said new pixel.
A hybrid interpolation method comprising:
- a plurality of interpolation algorithms that vary in complexity and performance;
- prediction means that predicts an appropriate interpolation algorithm, which provides a high quality image with a minimum processing time, for a new pixel to be interpolated;
- and
- performing means that chooses one of said plurality of interpolation algorithms according to said prediction means and performs interpolation for said new pixel.
