Aiming at problems such as grayscale discontinuous

contour fuzzy

large amount of calculation after interpolated

exists in traditional three kinds of image interpolation algorithms

propose a new regional interpolation algorithm.The algorithm first divides image according to flat or complex of image texture

then according to region the interpolation point belonging to in the source image correspondingly uses different interpolation algorithms.The simulation results verified that this algorithm can effectively reduces the operation time without changing the interpolation precision

compared with some typical interpolation algorithms.
