From: Interactive user correction of automatically detected onsets: approach and evaluation
Evolution of θ(t) throughout time as the result of user interaction in the sliding window percentile-based approach: symbol \(\left (\bigotimes \right)\) shows the ground truth onsets while (○) represents the performed interactions. Dashed and solid lines represent the static and interactive thresholds obtained with the sliding window approach, respectively. Initial percentile θ(t i =0) has been set to 50th (median value)
