Hi everyone,

I am working on a motion detection algorithm based on optical flow. Specifically, I am using the Dual TV L1 approach (createOptFlow_DualTVL1()). I would like to know if somebody have tried to use this method in realtime (with a "normal" computer). It is getting difficult to find the correct value for every different parameter and to get a solution working at 10 fps (more or less, which it would be my objective).

I know there are other optical flow methods, but I would want to do it with that particular one. Any help, solution and so on would be appreciated.

Thank you very much!!

I have used DualTV1 actually i'm still using it since i need to compute dense optical flow (velocty of every pixel). As far i know using DualTV1 for real time (10fps)is quite impossible in standard computer since it is compute the velocity if every pixel for every frame. here is what some one advice me if it helps.
