Abstract :
In this paper, our interpolation algorithm based on LAZ (locally adaptive zooming method) improves the cubic spline interpolation method. Its basic principles and implementation methods are discussed in detail. The simulation results of comparison with other traditional methods have demonstrated that this method emphasizes the visual effect of magnified image, especially for color ones.
