我们提出了一个算法提取对象描述的手绘草图记住的场景，绘制视频检索查询。我们的草图描绘场景内容，以及运动的指标。我们报告了一项探索性研究，调查人们如何描绘素描回忆的事件。我们将本研究的几个观察到一个新的草图解析算法的设计。我们利用一个时间HMM分类识别常见的象形图，和图形切割，以确定更一般的对象。
We present an algorithm for extracting object descriptions from free-hand sketches of remembered scenes, drawn as video retrieval queries. Our sketches depict scene content, as well as indicators of motion. We report an exploratory study investigating how people sketch to depict recalled events. We incorporate several observations from this study into the design of a novel sketch parsing algorithm. We draw upon a temporal HMM classifier to recognise common pictograms, and graph-cut to identify more general objects.
