In this paper, an image interpolation scheme is designed for 2D natural images. A local support rational cubic spline with control parameters, as interpolatory function, is being optimized using Genetic Algorithm (GA). GA is applied to determine the appropriate values of control parameter used in the description of rational cubic spline. Three stateof-the-art Image Quality Assessment (IQA) models with traditional one are involved for comparison with existing image interpolation schemes and
