Quality evaluation of the CBERS-02B high spatial resolution image

In this paper, we introduce some external parameters to attempt to build a suitable standard and to increase automation for quality evaluation of the CBERS-02B high spatial resolution image. The image quality of CBERS-02B was compared with SPOT-5 and P5 satellite in two ways of subjective evaluation and external evaluation. The subjective results show that the quality of SPOT-5 is better than CBERS-02B and P5, and the quality of CBERS-02B is similar to P5 for most land-cover types. The external evaluation gives us quantitative image quality. From the results, the subjective evaluation and the external evaluation are matched pretty well. The parameters introduced in this work are useful to quantitatively evaluate the image quality.
