Abstract
Resolution enhancement of digital images is one of the active research areas of all time. Images with better quality help in improving the performance of the image analytic systems with better accuracy rates. This article presents a digital image resolution enhancement system by employing A+ and Non-Local Means (NLM) filter. The A+ technique performs well with minimal storage and computational overhead, while increasing the resolution. Finally, NLM filter is applied to refine the resolution enhanced image and the performance of the proposed approach is tested in terms of PSNR and SSIM. The performance of the proposed approach is better, when compared to the existing approaches. © IAEME Publication.
