Abstract:
A method to generate a plurality of relevant spatiotemporal descriptors for a sequence of N-dimensional data sets, each data set including a plurality of scalar quantifies arranged in the N-dimensional coordinates and a temporal coordinate, where N is an integer, the method, comprising the steps of:(a) filtering a volume of die scalar quantities according to a plurality of oriented filter characteristics to produce a respective plurality of spatiotemporal filter values corresponding to the scalar quantities in the selected volume; and (b) determining the plurality of relevant spatiotemporal descriptors directly from the plurality of spatiotemporal filter values; wherein;at least one of the plurality of relevant spatiotemporal descriptors is determined from at least two of the plurality of spatiotemporal filter values; and the plurality of relevant spatiotemporal descriptors includes at least one descriptor of image information other than coherent motion.
