Obscurances, from which ambient occlusion is a particular case, is a technology that produces natural-looking lighting effects in a faster way than global illumination. Its application in volume visualization is of special interest since it permits us to generate a high quality rendering at a low cost. In this paper, we propose an obscurancebased framework that allows us to obtain realistic and illustrative volume visualizations in an interactive manner. Obscurances can include color bleeding effects without additional cost. Moreover, we obtain a saliency map from the gradient of obscurances and we show its application to enhance volume visualization and to select the most salient views This work has been supported by TIN2007-68066-C04-01 and TIN2007-67982-C02 of the Ministry of Education and Science (Spanish Government), by the MedViz Initiative in Bergen (medviz.uib.no), and by the Austrian Science Fund (FWF) grant no.
