1. A method for identifying a spatial location of an event within video image data comprising: receiving trajectory data of a trajectory of an object for an event within video image data; generating a set of compressed spatial representations of the trajectory data of the trajectory of the object for the event; generating a lossless contour code of the trajectory data of the trajectory of the object for the event; inputting each of the set of compressed spatial representations of the trajectory data of the trajectory of the object for the event and the lossless contour code of the trajectory data of the trajectory of the object for the event into a relational database; and searching the relational database to identify a spatial location of the event within the video image data.
