摘要
针对不同的云层厚度采用不同的去云方法,弥补了不同去云方法的欠缺;并详细研究了同态滤波法、替补法等在MODIS影像中云的去除效果,提出基于图像融合的方法对无云区数据进行了还原,保证了无云区信息不改变,去云效果明显。
In order to make up for the defects of different removing cloud methods, different methods to remove the cloud in images should be used according to different cloud thickness. Homomorphic filter algorithm and re- placement method, etc were studied on the results of removing cloud in MODIS images, and by using image fu- sion method the information of cloud-free areas was restored, which ensured that the information of cloud-free areas remained unchanged. The effect of removing cloud was very significant.
