چکیده

This article concentrates on a quality assessment for H.264 coded low-rate and low-resolution video sequences which are in particular of interest for mobile communication. The choice of appropriate setup for tests is discussed. The focus is given on the influence of the sequence character (spatial and temporal information). The data set is compared to various known video quality metrics. It is shown on the obtained data set, that it is not possible to separate the dynamic and static parameters without considering the character of the sequence and thus to create a universal metric.

Comparison of video codecs and coded video sequences quality using the latest objective and subjective assessment methods

This paper presents the comparisons of the latest subjective video sequence quality assessment methods versus objective quality assessment using H.261, H.263+ and H.264 advanced video coding (AVC). A Simultaneous Double Stimulus for Continuous Evaluation (SDSCE) method was used for subjective quality assessment. The Peak Signal to Noise Ratio (PSNR) method and the-state-of-the art Structural SI...

Video Quality Assessment Using Laplacian Modeling of Motion Vector Distribution in Mobile Video Stream

Video/Image quality assessment (VQA/IQA) is fundamental in various fields of video/image processing. VQA reflects the quality of a video as most people commonly perceive. This paper proposes a reducedreference mobile VQA, in which one-dimensional (1-D) motion vector (MV) distributions are used as features of videos. This paper focuses on reduction of data size using Laplacian modeling of MV dis...

A Full-Fuzzy Rate Controller for Variable Bit Rate Video

In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...

Scalable Motion-Adaptive Video Coding with Redundant Representations

This paper presents a scalable video coding scheme (MP3D), based on the use of a redundant 3-D spatio-temporal dictionary of functions. The spatial component of the dictionary consists of directional and anisotropically scaled functions, which form a rich collection of visual primitives. The temporal component is tuned to capture most of the energy along motion trajectories in the video sequenc...
