Abstract

A method for detecting motion is presented. The method includes identifying a region of interest in the plurality of images corresponding to a subject of interest. Furthermore, the method includes determining signal characteristics corresponding to the region of interest. In addition, the method includes generating a composite signal, where the composite signal comprises an aggregate of the signal characteristics corresponding to the region of interest, the method also includes analyzing the composite signal to detect motion in the region of interest.
