OmniMotion jointly tracks all points in a video across all frames, even through occlusions .
We present a new test-time optimization method for estimating dense and long-range motion from a video sequence. Prior optical flow or particle video tracking algorithms typically operate within limited temporal windows, struggling to track through occlusions and maintain global consistency of estimated motion trajectories. We propose a complete and globally consistent motion representation, dubbed OmniMotion , that allows for accurate, full-length motion estimation of every pixel in a video. OmniMotion rep
