| Abstract: | In academic aspect, various methods for digital image processing are formulated in detail. Then, a method which can automatically identify, calculate and generate all the controlled points is founded based on image processing and analysis. The experiments show that this method is simple, accurate, effective and makes a foundation for the full automation of geometric distortion work. At last, image is restored by using bilinear and grey-scale interpolation. |
