Quality Improvement of Beijing-1 Small Satellite Images

摘要

Striping noise and image degradation are the main factors that reduce the quality of Beijing-1 small satellite raw dataimages, thus noise removal and image restoration are the two important tasks in processing and application of theimages. This paper presents efficient noise removal and image restoration methods on analysis of the imaging systemcharacteristics and the image quality reduction principles. The proposed methods evidently improve quality of theimages, and are employed in practical processing procedures of Beijing-1 small satellite images.
