摘要: 针对红外视频时空显著性检测问题,提出一种基于Gestalt 优化的方法。设计基于多尺度局部稀疏表示和局部对比度测量的方法计算红外视频的空间显著性;为提取视频中显著性目标的运动信息, 设计基于多帧对称差分的算法计算时间显著性;为得到初始时空显著图, 设计基于交互一致性的融合策略将空间显著图和时间显著图进行自适应融合; 提出基于Gestalt 优化的最终时空显著图计算方法。实验结果表明,提出算法能有效检测红外视频的时空显著性。

Abstract: A spatiotemporal saliency detection method based on Gestalt optimization is proposed. A method based on the multi-scale local sparse representation and local contrast measure is proposed to compute the spatial saliency in the infrared videos. A multi-frame symmetric difference approach is adopted to detect the temporal saliency. To get the initial spatiotemporal saliency map, a scheme based on the mutual-consistency is designed to fuse the spatial and temporal saliency maps adaptively. A Gestalt-guided optimization method is designed to calculate the final spatiotemporal saliency map. Experimental results show that the proposed method can effectively detect the spatiotemporal saliency of infrared videos.
