Comparison of five methods. a The performance of all methods plotted on correlation vs. PSNR axis. As it can be seen from the graph SFlow and frame averaging performs well for large displacement optical flow compared to other methods. The performance of the proposed method tops other methods for correlation > 0.7 which includes majority of the cases. b and c shows Wilcoxon signed rank test for 90% of the sequences in-terms of hypothesis test and p-value
