Camera path

Open NatalyaSlepkova opened this issue 5 years ago • 2 comments

Thank you for your code. In your README you demonstrate plot of path's original video and stabilized. How do you get this paths? I thought that it's path of frame's center - x. So x' = H*x, where H is matrix homography and (x'[0] / x'[2], x'[1] / x'[2]) is new coordinates (x, y) of center next frame. But I get very strange plot. Could you explain me my mistake, please?

Thanks for your interest, As in the paper, not just a single camera path is computed for the whole frame, it is computed for each mesh in a frame. Motion vectors are computed for each mesh in a frame and are accumulated temporally, then using optimization module it smoothens camera path.
