| 摘 要： | 航空图像由于CCD相机距景物较远，所以图像分辨率较低，为了获得较高分辨率的数字图像，传统的方法就是要对原数字图像进行插值放大。本文提出了一种基于二维离散小波的图像放大方法，与传统插值方法相比，此方法既放大了图像提高了分辨率，又保持了原始图像的细节特征。从实验结果看，此方法是一种较好的提高航空图像分辨率的方法。

| Abstract: | Because the distance between CCD camera and scenery is very far, the resolution of aero-image is not good. To abtain high resolution d igital image, the methods of interpolation are usually used. A method of magnify ing image based on two dimension discrete wavelet is introduced. In this paper, compared with traditional interpolation methods, it not only enhanced resolution of the aero-image, but maintained the detail character of the image. Experiment results have shown that it is good method for enhancing aero-image. |
