Real-time elimination of brightness in color images by MS diagram and mathematical morphology

Abstract

This paper proposes a real-time method for the detection and elimination of brightness in color images. We use a 2D-histogram that allows us to relate the signals of luminance and saturation of a color image and to identify the specularities in a given area of the histogram. This is known as the MS diagram and it is constructed from a polar color model. We use a new connected vectorial filter based on color morphology to eliminate the brightness. This filter operates only in the bright zones previously detected, reducing the high cost of processing of connected filters and avoiding oversimplification, in single-processing and multiprocessing environments. © Springer-Verlag Berlin Heidelberg 2007.
