On the role of context in probabilistic models of visual saliency

In recent years, many principled probabilistic definitions for the de-termination of visual saliency have been proposed. Moreover, there has been increased focus on the role of context in the determination of visual salience. Prior efforts have shed some light on how context may help in predicting the location of, or presence of features associ-ated with an object in the context of detection or recognition. Never-theless, there remains a variety of manners in which context may be exploited towards providing better judgements of salient content. In this light, we investigate the role of context in the probabilistic deter-mination of salience while presenting a number of potential avenues for future research.
