While doing my preparations for my multimedia information systems lecture I finally came around to implement the visual attention model of Stentiford myself. I just check in the sources (SVN). The algorithm gives actually really nice results compared to its actual simplicity (implementationwise). You can see an example in the following figure. On the left hand side there is the original image and on the right hand side a visualization of the attention map. The light areas (especially the white ones) are deemed centers of attention. Sky and sand are so to say just random noise (there is a lot of “random” in this approach).
