Elliptical monogenic representation of color images and local frequency analysis
Résumé
We define a new color extension for the monogenic representation of images by using an elliptical tri-valued oscillation model jointly with the vector structure tensor formalism. The proposed method provides a rich local colorimetric and geometric analysis, in particular a color phase concept, which can be computed by a numerically stable algorithm. This representation is finally used to estimate the local frequency of color images.
