Software for video quality assessment
2016 39th International Conference on Telecommunications and Signal Processing (TSP), 2016This paper deals with objective video assessment methods. The paper begins with a short introduction to video quality evaluation methods. Mainly it is concentrated to common objective measurement methods including Peak to Signal Noise Ratio (PSNR), Structural Similarity (SSIM), and Mean-Singular Value Decomposition (M-SVD).

Video quality perception in telesurgery
2017 IEEE 19th International Workshop on Multimedia Signal Processing (MMSP), 2017Telesurgery enables an expert surgeon to assist a remote surgeon during a surgical intervention, which benefits patient care in resource-poor settings. In reality, videos of surgical procedures are compressed and transmitted over large distances in real time and, therefore, are subject to a wide variety of distortions.

Video classification for video quality prediction
Journal of Zhejiang University-SCIENCE A, 2006In this paper we propose a novel method for video quality prediction using video classification. In essence, our approach can serve two goals: (1) To measure the video quality of compressed video sequences without referencing to the original uncompressed videos, i.e., to realize No-Reference (NR) video quality evaluation; (2) To predict quality scores ...

Impact of Video Content on Video Quality for Video over Wireless Networks
2009 Fifth International Conference on Autonomic and Autonomous Systems, 2009Video streaming is a promising multimedia application and is gaining popularity over wireless/mobile communications. The quality of the video depends heavily on the type of content. The aim of the paper is threefold. First, video sequences are classified into groups representing different content types using cluster analysis based on the spatial (edges)

Video Quality Analysis for Concert Video Mashup Generation
2010Videos recorded by the audience in a concert provide natural and lively views from different angles. However, such recordings are generally incomplete and suffer from low signal quality due to poor lighting conditions and use of hand-held cameras. It is our objective to create an enriched video stream by combining high-quality segments from multiple ...

Video Quality Classsification Based Home Video Segmentation
2005 IEEE International Conference on Multimedia and Expo, 2005Home videos often have some abnormal camera motions, such as camera shaking and irregular camera motions, which cause the degradation of visual quality. To remove bad quality segments and automatic stabilize shaky ones are necessary steps for home video archiving.

Accurate video-quality estimation without video decoding
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010This paper proposes a video-quality estimation method which does not need video decoding. It takes into account error-concealment effectiveness and the location of video-quality degradation to estimate video-quality from only packet-header information.

An Objective Video Quality Metric for Compressed Stereoscopic Video
Circuits, Systems, and Signal Processing, 2011Stereoscopic video create the impression of depth by using two slightly different viewpoints. Conventional video quality assessment methods for 2D video are not suitable for stereoscopic video, so a new video quality assessment model for stereoscopic video is needed.

Perceivable artifacts in compressed video and their relation to video quality
Signal Processing: Image Communication, 2009Compressed video is degraded in quality due to the introduction of coding artifacts. A two-step subjective experiment was performed to evaluate the most visible artifacts and their relation to video quality for AVS and H.264 compressed video. In the first step, non-expert viewers were requested to score the image quality degradation as a function of ...

Fast Video Registration Method for Video Quality Assessment
2004In this paper, we propose a block-based video registration method that can be used for various applications such as objective video quality assessment. Instead of using the entire frames of a reference video sequence and a processed video sequence, we use a limited number of frames which are selected under a certain criterion and the selected frames ...
