Paper Abstract

We define a variational method to perform frame-fusion. The process is in three steps: we first estimate the velocities and occlusions using optical flow and spatial constraint on the velocities based on the L1 norm of the divergence. We then collect non-occluded points from the sequence, and estimate their locations at a chosen time, on which we perform the fusion. From this list of points, we reconstruct the super-frame by minimizing a total variation energy which forces the super-frame to look like each frame of the sequence (after shifting) and select among the least oscillatory solutions. We display some examples.
