摘要：
Nearest-neighbor, linear, and various cubic interpolation functions are frequently used in image resampling. Quadratic functions have been disregarded largely because they have been thought to introduce phase distortions. This is shown not to be the case, and a family of quadratic functions is derived, The interpolating member of this family has visual quality close to that of the Catmull-Rom cubic, get requires only 60% of the computation time.
