The Contributions of Image Content and Behavioral Relevancy to Overt Attention
Figure 8
(A) Time course of DKL values for high- and low-level features; these were computed for each fixations separately starting from the second fixation on.
Cornerness feature was used to illustrate the time-course of a low-level feature. While, absolute DKL values are shown in the left panel, the curves were normalized to their peak value (second fixation) in order to have a better comparison of the temporal evolution. (B) Joint distribution of fixation durations computed separately for Natural (left panel) and Urban (right panel) categories. (C) For different image categories, each bar represents the contribution of low- and high-level information on the variability of duration of fixations.
