Abstract
Image super-resolution (SR) is a fundamental problem in computer vision aimed at reconstructing high-resolution (HR) images from low-resolution (LR) inputs. Various methods have been proposed to solve this problem, ranging from traditional signal processing techniques to modern deep learning-based approaches. Two prominent methods in SR are Sparse Representation (SR) and the ASDS_AR (Attention-based Super-Resolution with Discriminative Spatial Attention Residuals) technique. Sparse representation, typically used with dictionary learning and sparse coding, models images as sparse combinations of learned atoms from a dictionary, allowing for the recovery of fine details. On the other hand, the ASDS_AR method leverages deep learning, particularly attention mechanisms and residual learning, to focus on important spatial regions and enhance the image resolution. This paper presents a comparative study of these two approaches in terms of their performance, computational efficiency, and ability to preserve fine image details. Through qualitative and quantitative evaluation on several benchmark datasets, we analyze the strengths and weaknesses of each method in terms of image quality, PSNR, SSIM, and perceptual metrics.
