This method implements a phase-based Opictal Flow Algorithm described in:
Gautama, T. and Van Hulle, M.M. (2002). A Phase-based Approach to the Estimation of the Optical Flow Field Using Spatial Filtering.IEEE Trans. Neural Networks, 13(5), 1127--1136.

This method is used for tracking wavelet/optical flow-based
detection for automatic target recognition in the following paper:

Version Published Release Notes
1.4.0.0

cleaned up grammar in description
1.3.0.0

Changed wavelet level window to a text box
Fixed playback bug
1.2.0.0
