I still remember that radial Blur was written in the past, but the results didn't seem good at the time. This time the results are acceptable. The algorithms used in the program are: 1. Calculate the R and angular ang distance between the current processing point and the image center point; 2. Radial blur is obtained by modifying R. 3. The rotation blur is obtained by modifying Ang. The code can be fully un
