File Information

Description

The code implements the optical 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.

The algo proceeds in 3 steps
1. spatial filtering
2. phase gradient estimation
3. IOC using recurrent networks

MATLAB release

MATLAB 5.3 (R11)

Other requirements

The code has been tested on Solaris (Matlab 5.3 R11), Linux (Matlab 6.0 R12) and on a Windows platform (Matlab 6.0 R12).

13 Nov 2008	OkinawaDolphin	It seems to be interesting, but I can't figure out how to open *.tar files on a Windows PC. Is there a ZIP file?

Updates
25 Oct 2002	added a bug report in the README file
12 Nov 2002	I have included a non-mex version, since the mex file didn't seem to yield correct results on a windows platform.
07 Jan 2003	I have added a precompiled mex version for windows
27 Jul 2004	Update of the algorithm itself: rather than using the goal programming network for solving the intersection-of-constraints, it now finds the solution analytically. Should have done this in the first place, but ah well ...
