Appraisement of CBERS-1 image quality with image information capacity and power spectrum

CBERS-1 images are assessed in this paper with image information capacity and power spectrum. Through comparison the same areas of CBERS-1 image and TM image, the CBERS-1 image quality is reflected impersonality. Experiments result shows that CBERS-1 image have the approximately same image quality as TM image both in information abundance and in texture feature, and it has fine image quality in comparison.
