File Information

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.


Phase Based Optical Flow inspired this file.

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

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.
