Supplementary Materials S2F: Slow-To-Fast Interpolator Flow

In this section we list all the threshold and parameters, and their numerical values, kept constant throughout each experiment. Together with the main body of the paper, this enables independent implementation and reproduction of the results. More importantly, we plan to release our implementation, so independent validation is straightforward. The three key threshold in our algorithm are: εr on residual, εc on compatibility check, and increment of radii δ. εr = 30 for all datasets (notice that we don’t calculate residuals based on RGB color space, instead we use Lab color space for more invariance to illumination change). And εc = 5, δ = 2 for both Sintel and Middlebury datasets; εc = 1, δ = 1 for Kitti dataset, which are inline with the parameter setting in [1].
