An implementaion of the very classical optical flow method of Horn & Schunck according to their paper:
Horn, B.K.P., and Schunck, B.G., Determining Optical Flow, AI(17), No. 1-3, August 1981, pp. 185-203
Sir, what will be the value of alpha and no of iterations for the demo run of these images provided in the file..pls reply
very good job
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?
thanks for sharing!
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?
Now includes the computeDerivatives function.
