Abstract: Evaluating the image perceptual quality is a fundamental problem in image and video processing, and various methods have been proposed for image quality assessment(IQA).This letter presents IQA metrics such as Conventional IQA indices ( mean squared error (MSE), signal-to-noise ratio (SNR) and peak signal-to-noise ratio (PSNR)), state-of-the-art IQA metrics(structural similarity based image quality assessment (SSIM),multi-scale-SSIM, non shift edge based ratio (NSER) and their limitations . In the non shift edge based ratio (NSER) method the procedures involved include computing the response of classical receptive fields, zero-crossing detection, and non-shift edge based ratio (NSER) calculation. This IQA metric is very simple but very effective and performs much better than most state-of-the-art IQA metric.
Keywords: Image quality assessment, structural similarity, non-shift edge, zero-crossing.
