We then describe visual features, in particular motion, and similarity measures adopted for retrieval.  ...  We present three levels of abstracting video content by scene, keyframe and key object representations. These representation schemes in overall serve as a good start for video retrieval.  ...  Besides the incapabilities in handling complicated transitions such as fancy wipe patterns, most approaches fail when motion is coupled with gradual transition.  ...
