.... instance, VideoTrails approach to analyzing a video clip involves first generating a trail of points in a multidimensional space where each point is derived from physical features of a single frame in the video clip[24] Spario temporal databases, which deal with geometries changing over time[28]. The above databases and the queries processed against them have the following characteristics in common: Entities in the databases are either spatial objects, or can be converted into spatial objects through feature extraction. Examples of feature vectors are color histograms[6] Fourier ....
