Supplementary Figure 4: AQuA detects ground truth events across three types of simulated data.

Color represents event count for each pixel (note colors bars have different scales in each dataset). Red borders show ROIs detected by ROI-based methods. (AQuA does not detect ROIs.) (a) Pure ROI. (b) Size change odds of 5, indicating size changes 20–500% of ROI. (c) Location change ratio of 1. Average distance to the center of the ROI is 100% the ROI diameter. (d) Mixed propagation with 10 frames.
