What type of velocity are these vectors representing on the image? Are they pixel velocities? If so, how do I go about averaging them and converting these values to something useful such as speed?

Hi Kharbat!
Uhm, Thanks for your code Sharing. I would like convert 2D video into 3D video by using optical flow. How can i use those optical flows in order to convert into depth map?

May I have a look?Ha Ha

Hi. Thanks for your nice code. Can you explain How did you find [-1 1; -1 1],... in computeDerivates.m file? thanks

Are you sure that the derivatives in the computeDerivates.m file are correct? Matlab stores images with the y-axis in the first dimension and the x-axis in the second, so I think that fx and fy might be the wrong way around...

how can i change the optical flow from pixel by pixel to 16x16?
