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
