Abstract

Systems and methods for adapting images for substantially optimal presentation by heterogeneous client display sizes are described. In one aspect, an image is modeled with respect to multiple visual attentions to generate respective attention objects for each of the visual attentions. For each of one or more image adaptation schemes, an objective measure of information fidelity (IF) is determined for a region R of the image. The objective measures are determined as a function of a resource constraint of the display device and as a function of a weighted sum of IF of each attention object in the region R. A substantially optimal adaptation scheme is then selected as a function of the calculated objective measures. The image is then adapted via the selected substantially optimal adaptation scheme to generate an adapted image as a function of at least the target area of the client display.
