A Novel Approach for Single Image Super Resolution by Sparse Signal Representation
نویسندگان
چکیده
This paper presents a new approach to obtain a high resolution image from a single image low resolution by a technique of sparse representation. Sparse representation is a way of representing a signal sparsely i.e. with fewer non zero elements. In this method we find the sparse representation of the input low resolution image patches and then use the coefficient of this representation to generate the high resolution image output.

Image Classification via Sparse Representation and Subspace Alignment
Image representation is a crucial problem in image processing where there exist many low-level representations of image, i.e., SIFT, HOG and so on. But there is a missing link across low-level and high-level semantic representations. In fact, traditional machine learning approaches, e.g., non-negative matrix factorization, sparse representation and principle component analysis are employed to d...
متن کاملImage Super-Resolution Based on Sparsity Prior via Smoothed l0 Norm
In this paper we aim to tackle the problem of reconstructing a high-resolution image from a single low-resolution input image, known as single image super-resolution. In the literature, sparse representation has been used to address this problem, where it is assumed that both low-resolution and high-resolution images share the same sparse representation over a pair of coupled jointly trained di...
متن کاملFusion of Thermal Infrared and Visible Images Based on Multi-scale Transform and Sparse Representation
Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...
متن کاملImage Super Resolution Using Sparse Image and Singular Values as Priors
In this paper single image superresolution problem using sparse data representation is described. Image super-resolution is ill posed inverse problem. Several methods have been proposed in the literature starting from simple interpolation techniques to learning based approach and under various regularization frame work. Recently many researchers have shown interest to super-resolve the image us...
متن کاملSingle Frame Image Super-resolution Based on Sparse Geometric Similarity ★
In this paper, we propose an image super-resolution approach based on sparse signal representation. The algorithm is based on two assumptions: one is the image patches have a sparse representation with respect to an over-complete dictionary of prototype signal atoms. Another is that geometric features from the High-resolution (HR) image patch to be reconstructed can learn from those of the avai...
