Abstract

We describe a color image transform which is capable of encoding spatio-chromatic image features. The method relies on the development of physical interpretations of complex image Fourier transforms allowing the direct extraction of spatio-chromatic structures from images. The process is analysed using an elliptical representation in order to determine filter characteristics and responses. Both a spatial and chromatic filter are developed and used on test images with results showing the ease with which this technique can be utilised.
