In this paper, an intelligent low-cost mode decision (MD) procedure is proposed for the inter-view frame of the multi-view video coding (MVC). Multiple parameters, such as macro block (MB) energy, view/temporal domain mode similarities and so on, are utilized to reduce the number of the mode candidates so that the corresponding Rate-to-Distortion Cost (RDCost) computing can be eliminated. The simulation...
In this paper, we propose a full reference (FR) video quality assessment (VQA) algorithm for the broadcasting multimedia signal. The relationships between the VQA parameters and the quality score obtained by the subjective human visual system (HVS) model of the distorted videos are investigated. Considering the high correlations and the importance of the VQA parameters, a new FR VQA algorithmis worked...
The VQM (Video Quality Measurement) scheme is a methodology that measures the difference of quality between the distorted video signal and the reference video signal. In this paper, we propose a novel video quality measurement method that extracts features in DCT (Discrete Cosine Transform) domain of H.263 SDTV. Main idea of the proposed method is to utilize the texture pattern and edge oriented information...
In this paper, we proposed a reference-free (RF) objective measurement algorithm for the digital video signals of multimedia communication. With the statistical analysis, we utilized the important feature vectors (FVs) which have high relationships with the subjective perceptual quality of digital video sequences. After considering the fundamentality and force of these FVs, we combined them with different...
Recently H.264/AVC is rapidly deployed in the mobile multimedia market, such as terrestrial and satellite DMB (digital multimedia broadcasting), and Internet multimedia streaming systems. To provide the better quality under the unreliable communication environments, we propose a motion vector (MV) recovery method for the temporal error concealment. The H.264/AVC adopts the various block sizes for...
