1. A method comprising: modeling an image with respect to multiple visual attentions to generate a respective set of attention objects (AOs) for each attention of the visual attentions; analyzing the attention objects and corresponding attributes to optimize a rate of information gain as a function of information unit cost in terms of time associated with multiple image browsing modes; and responsive to analyzing the attention objects, generating a browsing path to select ones of the attention objects, the browsing path being a trade off of time for space or space for time.
