Wasserstein metrics show improved noise resilience for image similarity

A new paper explores the sensitivity of Wasserstein metrics to noise in image similarity scoring. Researchers derived bounds showing that the error in Wasserstein discrepancy scales with the square root of noise standard deviation, which is more favorable than the linear scaling of the Euclidean metric. Experiments support these findings, demonstrating that Wasserstein metrics can effectively capture data geometry in noisy conditions, even outperforming Euclidean metrics in cases like cryo-electron microscopy images.
