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
I am a new to matlab.
(1):What is the use of 'yosemite/correct_yosemite256'file ?And, how to creat a file like it using the other video sequences.?
(2)I don't understand this code :[Cx, Cy] = read_flow ('yosemite/correct_yosemite256');
This a good piece of code.. As a part of my thesis,I have to find out the flow vectors for any 2 consecutive frames in a video sequence using phase based approach which is exactly similar to your work.How can i read the .bmp or .jpeg files?
How can I use this on .bmp or .jpg files instead of default files?
How can I use this on Bitmaps (.bmp) instead of .ras Files??
Really do a good job, thank you very much
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?
The entire code contains good features of optical flow.
that is good
thank you very much
many thanks for cooperation
I will make good use of it
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 ...
I have added a precompiled mex version for windows
I have included a non-mex version, since the mex file didn't seem to yield correct results on a windows platform.
added a bug report in the README file
