Hello Olivia,

Please do not hesitate to correct me if I am wrong. As the images are 3D, optical flow vectors are 3D too. Consequently, each vector has derivatives along three Cartesian coordinates (Ix, Iy and Iz).

Hello, your scripts are very helpful, but I have a question for the sub-function 'imageDerivatives3D'. I don't quite get why the derivatives Ix, Iy and Iz are calculated using the two images. Could you please explain it for me or offer a ref? Thank you very much.
