MASKING EFFECT IN VISUAL ATTENTION MODELING
Olivier Le Meur, Patrick Le Callet, Dominique Barba, Dominique Thoreau, Christian Pauc · 2004
In this paper, we focus on a bottom-up model of visual attention permitting to determine conspicuous locations on still color pictures. Such a model is useful to define visual regions of interest allowing to drive for instance a video coding scheme. The aim of this paper is not to provide a full description of the model (wholly described in [1]), but specially to assess the influence of a particular property of the human visual system (HVS) inserted in our model. The property that we want to emphasize here refers to the visual masking abilities of the HVS. Such property is a key step in many applications, including watermarking and video quality assessment. We provide evidences on the fact that visual masking influences the determination of conspicuous locations.
