Fixation density map
WebApr 26, 2024 · It is argued that fixation density, defined as the number of gaze points divided by the total area of a fixation event, can serve as a proxy for information processing and has a significant relationship with pupil data and fixation duration, which have been shown to be representative of cognitive effort and information processing. WebSep 25, 2015 · The saliency map is a smoothed fixation map by a Gaussian kernel of σ = 10 which produces a compact and accurate representation of fixation density and normalizes the map to [0, 1].

WebFeb 2, 2012 · To ensure that summation of fixation maps across different face trials produced spatially meaningful density maps, fixation maps for individual faces were first aligned to a common reference frame using simple translations only. This reference frame was defined by the internal facial features. Specifically, the alignment minimized the sum …
