WebDec 8, 2024 · The goal of Optimal Transport as a mathematical gem at the interface between probability, analysis and optimization is to find the least costly transport. This work reviews this field with a bias toward numerical methods and their applications in computer graphics, and sheds lights on the impact of the given distance on the final result. Article WebOptimal transport is nowadays a major statistical tool for computer vision and image processing. It may be used for measuring similarity between features, matching and averaging features or registrating images. However, a major drawback of this framework is the lack of regularity of the transport map and the robustness to outliers.
