Saliency Region and Motion Characteristics Combined Video Quality Assessment
نویسندگان
چکیده
In order to accurately evaluate the video quality and make it consistent with the subjective evaluation result, a saliency region and motion characteristics combined video quality assessment is proposed in this paper. This method is based on traditional SSIM and improves its assessment performance. According to the relationship between human visual attention and video’s region of saliency, frame saliency is weighted by spatial saliency and temporal motion characteristics, in which the spatial saliency is extracted by spectrum analysis and the temporal one got by motion visual attention model. This saliency is weighted by SSIM index for single frame quality assessment. Finally, based on HVS characteristics and motion characteristics, the entire video quality SMWSSIM can be got by weighting single-frame quality. Experiment results prove that this method is faster, more convenient and accurate than other SSIM-based assessments.

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...
