摘要:

针对遥感图像插值要求,尽可能保持原图像信息,提高图像分辨率,并适合人眼观察的特点,提出适合于遥感图像的小波双线性插值方法.实验表明,与双线性插值相比,该算法得到较高的信噪比和较好的图像效果.

Abstract:

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
