Image interpolation algorithm for digital image processing is an important element. In digital image processing, interpolation is a basic and most commonly used geometric computing, It is not only a wide range of applications, but also directly affect the accuracy of interpolation of the final image processing results, the best interpolation algorithm to explore the academic and applications are important. In this paper, image scaling, image distortion and image rotation has been used three kinds of image interpolation algorithms, and VC + + to achieve the three kinds of algorithms are compared .
Key words: Image interpolation ,the interpolation algorithm,VC
