A novel method for generating HR image using PDTDFB and interpolation

In this paper a novel method for generating HR (High Resolution) image using PDTDFB (Pyramidal Dual-Tree Directional Filter Bank) and Interpolation has been adopted. Generally, in digital images since the different kinds of noise highly affects various image processing techniques it is always better to perform denoising first. Here, first of all the image is decomposed into two different layers namely low pass sub band and high pass sub band after which denoising is being performed on both the layers so as to smoothen the image. The smoothened image is then interpolated using edge-preserving interpolation and then amplified. Finally, the HR image is being obtained by performing image composition.
