An Objective Approach to Assessing Relative Perceptual Quality of MPEG-Encoded Video Sequences
نویسندگان
چکیده
A novel objective approach to assessing the relative perceptual quality of MPEG-encoded video sequences is presented. Quality comparison of the original and filtered MPEG-encoded video sequences is performed directly in the frequency domain. Experimental results show a very good correlation between the objective quality measurement and the human subjective perception. This objective approach provides a sensible and meaningful automated quality measure for MPEG compression. The approach should become a viable tool to aid MPEG encoding optimization.

متن کاملPerceptually-evaluated loss-delay controlled adaptive transmission of MPEG video over IP
This paper presents the Adaptive Video over IP (AViP) approach to transmit video sequences. A rate-selection algorithm based on both delay and loss indications is presented and its performance measured using actual MPEG-2 video sequences, networks simulations and objective measures of perceptual quality. The results show that the AViP approach leads to efficient use of available network resourc...

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 ...
متن کاملA New Unequal Error Protection Technique Based on the Mutual Information of the MPEG-4 Video Frames over Wireless Networks
The performance of video transmission over wireless channels is limited by the channel noise. Thus many error resilience tools have been incorporated into the MPEG-4 video compression method. In addition to these tools, the unequal error protection (UEP) technique has been proposed to protect the different parts in an MPEG-4 video packet with different channel coding rates based on the rate...
متن کاملA framework for end-to-end video quality prediction of MPEG video
This paper proposes, describes and evaluates a novel framework for video quality prediction of MPEG-based video services, considering the perceptual degradation that is introduced by the encoding process and the provision of the encoded signal over an error prone wireless or wire-line network. The concept of video quality prediction is considered in this work, according to which the encoding pa...
