Understanding Popout: Pre-attentive Segmentation Through Non-Directional Repulsion

This white paper document identifies two measures which are to mark conspicuous image locations such as region boundaries, smooth contours and pop out targets against backgrounds, with attraction and non-directional repulsion, and unifies the dual processes of association by attraction and segregation by repulsion in one grouping framework. The paper generalizes normalized cuts to multi-way partitioning with these dual measures and shows that the criterion can be viewed as a stochastic jump-diffusion process, where the probability of jump is determined by the relative strengths of attraction and repulsion.
