This paper uses the opportunity given by the formalism of geometric algebras to perform colour image processing by describing one colour with a geometric vector in the 3D space. The paper proposes to manipulate colours in the RGB space where properties such as saturation or luminance can be described with the help of geometric operations. These geometric operations are applied on vectors encoded in...
We propose a new color extension of the monogenic wavelet transform. Monogenic wavelets give a coherent representation of scalar images through a local phase concept and an underlying orientation analysis. We here define a color extension of the monogenic framework. The underlying local geometric analysis and phase concept are generalized by using the color structure tensor. Resulting transform appears...
