Queen Mary Multi-Camera Distributed Traffic Scenes Dataset (QMDTS) is released for research purpose only. http://www.eecs.qmul.ac.uk/~xx302 by Alex Xun Xu 16, Sep 2015 List of contents: # QMDTS_Videos.zip ---- contains train and test raw videos for 27 scenes introduced in [1]. Train videos are used to learn local topics while test videos are used for behaviour profiling, query by example, cross-scene classification and multi-scene summarization. # ReferenceAnnotation.mat ---- contains the annotations for 112 clips for each of Scene 7, 8, 9, 10, 18 and 19. Feature Extraction: It is recommended to use Liu Ce's optical flow code [2] for computing visual features. A python implementation can be found at [3]. The codebook construction and bag of words feature generation can be found in the paper [1] Experiment section. Ref: [1] X. Xu, T. Hospedales, S.
