Color perception is a fascinating field of research which has inspired variational models for color correction. Recently, geometric approaches were added to the models to fit better with the human visual system, to treat various color spaces and to transport colors between images. The minisymposium will address recent developments in the field of geometrical color image processing reaching from the perception of brightness in color images, color enhancement and restoration in different color spaces to the colorization of images based on their geometry.
