We use in this paper the formalism of Clifford algebras to define the so-called Color Monogenic Signal associated to a color image. It consists in a function with values in the Clifford algebra &#x211D;<inf>5,0</inf> that codes color (RGB) and geometric structures information. Using geometric calculus, a notion of local color phase is introduced,(More)
In this paper, we present an interactive algorithm for segmentation of color images. The user first draws some scribbles into regions that must be discriminated, and the segmentation is then automatically obtained. The segmentation is based on the computation of geodesic distances within color monogenic signal (CMS) fields. An important difference with(More)
