Sample temporal cumulative opportunity error (TCOE) computation for a video of 70 seconds, with an example of 10-second segment, \(D=10 \gamma\), where \(\gamma\) is the frame rate of the video in frames per second. When computing TCOE, all segments of \(D=\{10,20,30,60,90,120\} \gamma\) frames (i.e., segments of 10, 20, 30, 60, 90, 120-second durations) within the video are used
