我们提出了一种新的基于内容的视频检索（CBVR）系统，由手绘草图查询描绘的对象和他们的运动（通过动态线索，条纹线和箭头）。我们的主要贡献是一个概率模型的视频剪辑（基于线性动力系统），导致一个算法匹配描述的草图对象的视频。我们展示了我们的模型拟合静态和移动相机条件下的剪辑，表现出线性和振荡运动。我们评估检索两个真实的视频数据集，并在一个视频数据集表现出控制变化的形状，颜色，运动和混乱。
We present a novel Content Based Video Retrieval (CBVR) system, driven by free-hand sketch queries depicting both objects and their movement (via dynamic cues; streak-lines and arrows). Our main contribution is a probabilistic model of video clips (based on Linear Dynamical Systems), leading to an algorithm for matching descriptions of sketched objects to video. We demonstrate our model fitting to clips under static and moving camera conditions, exhibiting linear and oscillatory motion. We evaluate retrieval on two real video data sets, and on a video data set exhibiting controlled variation in shape, color, motion and clutter.
