چکیده

We tested how to improve the quality of the reconstructed video, several deblocking algorithms have been used. In this paper, we will introduce these deblocking algorithms and classify them into several categories. On the other hand, the conventional PSNR is widely adopted for estimating the quality of the compressed video. However, PSNR sometimes does not reveal the quality perceived by human visual system (HVS). In this paper, we will introduce one measurement to estimate the blockiness in the compressed video.

A Machine Learning Approach to No-Reference Objective Video Quality Assessment for High Definition Resources

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

Reduced-Reference Image Quality Assessment based on saliency region extraction

In this paper, a novel saliency theory based RR-IQA metric is introduced. As the human visual system is sensitive to the salient region, evaluating the image quality based on the salient region could increase the accuracy of the algorithm. In order to extract the salient regions, we use blob decomposition (BD) tool as a texture component descriptor. A new method for blob decomposition is propos...

No-Reference Video Quality Assessment

Methods to assess the visual quality of digital videos as perceived by human observers are becoming important, due to large number of applications that target humans as the end users of video. In this paper a no-reference video quality assessment (VQA) algorithm is introduced. Characteristics of human visual system (HVS) is taken into considerations. The quality of video is calculated in compre...
