本文提出了一种对卫星遥感数字图像进行图质改善处理的既简单又节省时间的方法（二维ＲＧＳ法），用此方法进行处理的结果与常用的ＭＴＦ处理结果相比较，有以下几个优点：①操作简单，很容易地处理得到良好的图像图质改善处理效果。②不花费操作时间只调整两个参数很快就能得到理想的图质改善图像，ＣＰＵ时间也比ＭＴＦ处理明显减少。③对不同分辨率图像也有良好的改善处理效果。
This paper presents a simple and time-saving method (2D RGS method) for image quality improvement of satellite remote sensing digital images. Compared with the commonly used MTF processing results, the following two methods Advantages: ① simple operation, easy to deal with get a good image quality to improve the processing effect. ② do not spend operating time only adjust the two parameters will soon be able to get the ideal picture quality to improve the image, CPU time is also significantly reduced than the MTF processing. ③ different resolution images also have a good deal of improvement effect.
