Abstract
In this paper, an enhanced super-resolution image reconstruction method based on Markov random field (MRF) is proposed. This work incorporates an efficient training set. The most appropriate training set is utilized to find the similar patches based on the associated local activity of the image patch to improve the quality of reconstruction and to reduce the computational overload. Secondly, locality-sensitive hashing (LSH) method is used to search the similar patches from the training set. Finally, a robust and transformation invariant similarity measure named Image Euclidean distance (IMED) is incorporated to measure the patch similarity. Unlike traditional Euclidean distance, IMED measure considers the spatial relationships of pixels and provides an instinctively reasonable result. Experimental results demonstrate the outperforming nature of the proposed method in terms of reconstruction quality and computational time than several existing state-of-the-art methods.
