Lucas Kanade optic flow
Hello every one,
I have got a question about how to use the "VLIB_trackFeaturesLucasKanade_7x7" function.
I have two successive images of 160 x 160 pixels from a video camera.
I detect the good features to track using VLIB function : "VLIB_harrisScore_7x7"
That work fine.
But after I want to track the points using the Lucas-Kanade method and I same results in outx and x, and outy and y.
But when I try with OPENCV on PC computer I use the Harris VLIB function for corner detection and Lucas-Kanade OPENCV function that work fine.
In the OPENCV function, they use a pyramid image.
Did anyone has an idea how to use correctly the "VLIB_trackFeaturesLucasKanade_7x7" function
Thanks a lot
Please provide your email id.

I have the same question. Please send me demo code for Lucas Kanade function too. My email: email@example.com.
I sent you the demo project.
But I think it bounced back because of security settings of your mail server.
Could you provide an alternate email id?
Thank you very much.
Same problem here. Would be great if you could send me a demo :)
thanks a lot!
