A feedforward mechanism for human-like contour integration

Human sensitivity to global curvature.
(A) Variation in global curvature (β) across a range of contour stimuli used in the study, with β values set at 15°, 30°, 45°, 60°, and 75°, demonstrating straighter to more curved contours. (B) Sequence of a 2-IFC contour detection trial where participants identify the display containing the contour. (C) Mean accuracy of participants for contour detection across varying β conditions, with error bars representing 95% confidence intervals of the mean accuracy bootstrapped across participants. (D) Bar graph showing the variability in human performance across individual trials within each β condition.
