| Abstract: | Based on the feature of the knife - edge image, this paper uses the median filter, the method of mean dissect - lines and part filter to preprocess the noise in the image, and it makes a fine filter - noise effect , decreases the loss of useful information in the image, enhances the accuracy of the MTF of the CCD imaging measure system. Experiment indicates that the data processing method used in this paper can enhance the accuracy of the MTF of the CCD imaging measure system efficiently. |
