People counting results in terms of temporal cumulative opportunity error (TCOE) for different segment duration (segm.) with Algorithm 3 (A3: light green line), Algorithm 4 (A4: dark green line); and Commercial off-the-shelf 1 (C1: light grey line), and Commercial off-the-shelf 2 (C2: dark grey line). The x-axes are in logarithmic scale. We do not show the results for detectors (A1–2) as they obtain a TCOE several orders of magnitude larger than the rest of the algorithms. The company developing C2 defines OTS as any person within the field of view, differently than the definition proposed in this paper. To have this into consideration, we show two line plots for C2. The one with the highest error corresponds to using the definition proposed in this paper, and the other line using the definition proposed by C2
