小波方法在CCD图像处理中的应用

An Application of Wavelet Transform Method to CCD Image Processing

针对天王星卫星位置观测图像中存在的一些问题 ,提出了一种新的图像处理方法 ,即二维墨西哥帽小波变换方法。图像处理结果表明 ,这种方法能够有效地去除背景梯度和噪声 ,将接近主星的卫星从主星的光晕中分离出来。

A new method of CCD image processing,two dimensions Mexican Hat wavelet transform,is put forward for the purpose of improving the quality of the CCD images of uranian satellites.The results show that the background gradient and noises of Miranda are removed successfully and the satellite nearer to the primary can be separated from the halo of the primary.
