Optimal transport for image processing
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. 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

WebImage registration is the process of establishing a common geometric reference frame between two or more image data sets possibly taken at different times. In this paper we present a method for computing elastic registration and warping maps based on the Monge–Kantorovich theory of optimal mass transport. WebSep 24, 2024 · The OTDD relies on optimal transport (OT), a flexible geometric method for comparing probability distributions, and can be used to compare any two datasets, regardless of whether their label sets are directly comparable. As a bonus, the OTDD returns a coupling of the two datasets being compared, which can be understood as a set of soft ...
