%X Conventional improved interpolation introduces blurs,jagged edges,or artifacts.The Joint Bilateral Interpolation (JBI) is proposed in this paper.The low-resolution (LR) input image is first being interpolated with a fast and simple algorithm and then the interpolated result is used as a guidance image to apply the joint bilateral filter to upsample the LR image.And the parameters of Gaussian kernel function are given in the paper.Experiment results demonstrate that our new interpolation algorithm substantially improves the quality of the interpolated images and costs less calculation time than most existing nonlinear improved interpolation algorithms.
