Abstract :

Conventionally, image quality assessment (IQA) algorithms represent image quality as linearity with a “reference” or “perfect” image. Obvious drawback of this method is that the many times original image may not be accessible for the QA algorithm. This paper proposes an image quality assessment of natural-scene statistic-based on DCT score prediction approach. It operates in transform domain. Major artifacts like ringing, blocking and blur are observed in image quality assessment technique. In this paper DCT is used to extract different features of the image. We train and test our algorithm on LIVE database with respective subjective mean opinion score (MOS) on scale of (1-10) and manifest that the recommended work has good regularity with subjective interpret values and the objective estimation results. This paper well replicates the visual quality of images as well as quantifies possible losses of “naturalness” in the image. This paper presents a statistical approach for image quality analysis. In this approach degradation in an image are explored through DCT and wavelet transformation of images and computing statistical parameters like mean, standard deviation, skewness and kurtosis
