摘　　要：提出了一种新的基于频域分析的视频显著性计算模型。该模型具有计算量小、速度快的优点。首先将原始视频处理成一系列视频场景图片;然后根据频域分析方法分别计算视频的空域显著图和时域显著图,并用Renyi熵度量显著图的显著性;最后,融合时域和空域显著性结果,得到视频的显著性曲线。将本文模型应用于视频广告插入系统中并与现有方法比较,结果证明了其有效性。This paper proposes a novel video saliency computational model based on frequency domain analysis, which is simple and efficient. First, the original video is parsed to a series of consecutive video scene images. Then, the space domain saliency and time domain saliency of the video scene images are computed, respectively. In each domain, the saliency of each frame is estimated by using Renyi entropy. Finally, both space domain and time domain results are fused to obtain the overall saliency. Application results in video advertising system and comparison with state-of-the-art approach demonstrate the effectiveness of the proposed model.
