摘要

在地面被厚厚的云层覆盖的日子里,光学卫星获取的图像通常会出现信息缺失,因为我们在云层覆盖下看不到任何东西而无法使用。为了恢复丢失的数据,人们提出了许多方法,但这些方法都只是从一幅或多幅看似是参考图像的图像中恢复图像,而且这些方法大多是选择相似的部分或对应的像素来恢复原始损坏的图像。本研究提出了一种利用周期性天气模式恢复受损图像的新方法。主要思想是结合预测和重建技术。对于预测,将使用连续图像的时间序列数据来预测下一个图像。该图像将作为重建过程的参考图像。

Recover Water Bodies in Multi-spectral Satellite Images with Deep Neural Nets
On the days that surface is covered by thick clouds, the acquired images from optical satellites usually suffer missing information, caused to not able to use because we can't see anything under cloudy cover. Many methods have been proposed in order to recover the missing data, but those only recover the image from one or more images that seem to be referenced images, and those approaches mostly select the similar part or corresponding pixels to recover the original damaged. This research proposes a new approach for recovering damaged image, which aims to use this periodical weather pattern. The main idea is combining prediction and reconstruction techniques. For prediction, A time-series data of consecutive images will be used to predict the next image. This image will be used as referenced image for reconstruction process.
