The sky in the exposures was de-rotated to compensate for the rotation of Earth, then images were stacked together producing an image identical to a single exposure but with less digital noise.
Based on the linear memory construction of digital image, this paper presents a method of fast realization of image rotation.
基于图像的线性存储结构，提出了一种图像旋转的快速实现方法。
