本文是在O.R.Mitchell(1977)关于滤除卫星照片中云的掩盖一文的基础上,对去云的问题进行了进一步的研究。本文的发展有以下三点:(1)重新推导了关于云层失真的数学模型;(2)以新推出的数学模型为基础提出了两级滤波的处理方案;(3)提出了一种噪声抵消法和一种三维处理方案。对以上设想做了部分实验验证,在微型机上做了计算机模拟实验,还在S101图像处理系统上进行了正式实验,取得了初步有效的实验结果。
This article is based on the article by O.R. Mitchell (1977) on filtering cloud cover in satellite photos and further studies on cloud removal. The development of this paper has the following three points: (1) Redefinite the mathematical model of cloud distortion; (2) Propose a two-stage filtering scheme based on the new mathematical model; (3) Propose a noise cancellation Method and a three-dimensional processing scheme. Part of the experimental verification of the above ideas was done, a computer simulation experiment was carried out in the microcomputer, and an official experiment was also carried out on the S101 image processing system, and preliminary and effective experimental results were obtained.
