Abstract

Experimental results are presented evaluating two wavelet- based gaze-contingent video resolution degradation methods under three foveal Region of Interest (ROI) placement strategies. ROI placement is described by the introduction of a novel visualization of viewers' scanpaths, termed Volumes of Interest (VOIs). VOIs represent foveal loci of gaze in 3D space-time. Three ROI placement strategies, ideal, preattentive, and aggregate, are used to determine the location of an unprocessed, dynamic spatial resolution region corresponding to the projected dimension of the fovea. Results indicate imperceptible degradation effects of both ideal and preattentive strategies under a visual tracking paradigm.
