1. A method for detection of independent motion of a plurality of objects presented in a time sequence of images acquired from different perspectives, comprising: a) processing the plurality of images with an automated processor to generate a linear system representing the plurality of objects in the form of a matrix D having at least three dimensions stored in a memory; b) analyzing the stored matrix D with an automated processor to qualitatively determine the consistency of said linear system based on a relationship of respective rank of the matrix D an augmented matrix DB, substantially without quantitatively solving said linear system consistency being represented as a decision; and c) outputting the consistency decision, representing whether or not there is independent motion between the plurality of objects represented in the time sequence of images.
