| Abstract: | In the paper,the importance of in-flight MTF estimation value in the field of image processing is firstly introduced.And then several estimation methods and their character,applicability,arithmetic and their specific indexes are analyzed.Based on that,the most easily-operated methods are presented.Subsequently we use the image of CBERS-02 CCD as the test object,and deduce several influence factors.Lastly,we try using the test result for image restoration and get image with more detailed information. |
