A color image sent to a monochrome output device must undergo a color-to-grayscale transformation. Such a transform typically retains the luminance channel or a derivative thereof...
A synchronizing word of a deterministic automaton is a word in the alphabet of colors (considered as letters) of its edges that maps the automaton to a single state. A coloring of...

In this paper, we prove that the harmonious coloring problem is NP-complete for connected interval and permutation graphs. Given a simple graph G, a harmonious coloring of G is a ...

Abstract. Color constancy and chromatic edge detection are fundamental problems in artificial vision. In this paper1 we present a way to provide a visualization of color constancy...
