Remote sensing image interpolation requires preserving the information of source image as much as possible, improving the image resolution, being appropriate for people to observe, and so forth. Presents wavelet bilinear interpolation algorithm, which is suit to remote sensing image. It has been found that the algorithm can obtain higher SNR and better image effect compared with bilinear interpolation.
Key words： wavelet transform; image interpolation; esemble transform
