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:
Dessauer, M. and Dua S. “Wavelet-based optical flow object detection, motion estimation, and tracking on moving vehicles”
Proc. Conf. SPIE Defense, Security, and Sensing. 7694-56. April 5-9, 2010.

Updates

1.4

cleaned up grammar in description

1.3

Changed wavelet level window to a text box
Fixed playback bug

1.2

added .fig file

Warning! The GUI is initially set to wavelet level=0 which requires substantial computation to complete. Try changing wavelet level to a high number to quickly run the optical flow calculation.

1.1

Updated the quiver axis to update to correct frame when the slider position is manual changed.
