Abstract
Super resolution is the process of reconstructing high resolution(HR) image from multiple low resolution(LR) images of a scene . LR images are at a specific pixel shift from each other. High Resolution(HR) grids are formed from these LR images using Stationary Wavelet Transform (SWT) by image registration. Interpolation of the missing pixel in the HR grid is done using Curvelet Transform(CT). Experimental results show that our method has got high PSNR compared to Curvelet Transform based super resolution. Also, it is verified that there is no need of filter to avoid interpolation errors
