Optimal transport for image processing

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. WebMar 5, 2024 · Optimal transport is the general problem of moving one distribution of mass to another as efficiently as possible. For example, think of using a pile of dirt to fill a hole …

Optimal transport as a metric between two color images

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. WebHis current research interests include image processing and machine learning methods related to optimal transport, which can be applied to biomedical imaging and biomarker discovery. Gustavo K.
