This paper proposes a novel approach to construct saliency map of color contrast and an enhanced technique for inhibition of return on this map for artificial visual attention. The ability to handle dynamic scenes is also included in the model by introducing a memory based mechanism. For the process of color map construction the traditionally followed concept of double-opponent colors is extended by implementing the concepts of contrast from the subject of color theory. In context of inhibition of return, the color based inhibition is also modeled according to recent research in human vision apart from the commonly implemented spatial inhibition. The proposed methods have produced results compatible with the existing models of visual attention whereas the region-based nature of the proposed technique renders advantages of precise localization of the foci of attention, proper representation of the shapes of the attended objects, and accelerated computation time.
