A novel hybrid method using Adaptive Wiener Filter and Example-based Approaches for aerial image super-resolution

A novel hybrid method is proposed for aerial image super-resolution in which the output of the Adaptive Wiener Filter (AWF) based super resolution technique is further enhanced using Example-based Super-Resolution (EBSR). While AWF method gives a reasonable result measured in terms of perceptual quality, it has a disadvantage of blurring the image on account of the weighted averaging. Introduction of EBSR compensates for the loss of high frequency content and results in sharpening the edges. This paper demonstrates the effectiveness of the hybrid approach in improving the overall performance.
