| 摘 要： | 文章从信息容量和图像功率谱这两个方面评价了CBERS-1的图像质量。并通过将同一地区的CBERS-1图像和TM图像进行比较,客现反映了CBERS-1卫星的图像质量。实验结果表明CBERS-1图像在信息丰富程度和图像综合的纹理特征上与TM图像质量相当,具有很好的可比性。

| Abstract: | CBERS - 1 images are appraised in this paper with image information capacity and power spectrum. Through comparison the same area's CBERS - 1 images and TM image, the CBERS - 1 image quality is reflected impersonality.Experiments result shows that CBERS- 1 images 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. |
