Image registration using optimal transport - INSA Lyon

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. Web(the template space) that will be adequate for the registration itself or for further processing (e.g. image analysis or image statistics). In order to nd this new latent common space, we propose to use Wasserstein barycenter[2] method based on the optimal transportation theory[5]. Optimal transport signed word range

Optimal Transport for Applied Mathematicians - Springer

WebThese two features are crucial for image processing tasks where one must take into account families of multimodal histograms with large mass variation across modes. The corresponding relaxed and regularized transportation problem is the solution of a convex optimization problem. Optimal transport is a fascinating topic and we only covered the very basics. If you want to know more about it and its applications in statistics, I can recommend “An Invitation to Statistics in Wasserstein Space”.

We might wonder how much effort it will take. So we start with … See more “Okay, okay, so we have all this transportation theory stuff, but how is it connected to the pictures from the beginning?” I’m glad you ask, let me explain. For … See more Good. Now we covered (a tiny part of) the theory, but how can we actually transport the colors? The easiest way would be to use the optimal transport package … See more WebThe role of optimal transport in applied mathematics is dramatically increasing, with applications in economics, finance, potential games, image processing and fluid … the prow restaurant banff
