Metric tensor for multicomponent edge detection
Sylvain Rousseau, David Helbert, Philippe C. Carré, Jacques Blanc-Talon · 2010
In this paper, we present the use of differential geometry for the segmentation of multispectral images, which allows us to unify several known methods including projecting onto a particular axis or a particular plan. This is done by choosing a metric tensor on the feature space computing the pullback of the metric tensor and applying standard Di Zenzo algorithm.
