چکیده
|
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 state-of-the-art image quality assessment (iqa) models with traditional one are involved for comparison with existing image interpolation schemes and perceptual quality check of resulting images. the results show that the proposed scheme is better than the existing ones in comparison. © 2016,pak.j.stat.oper.res. all rights reserved.
