People counting results in terms of temporal cumulative opportunity error (TCOE) for Algorithm 1 (red line), Algorithm 2 (dark red line), Algorithm 3 (light green line), and Algorithm 4 (dark green line). The shaded area indicates the standard deviation of the error, and the line the mean error. The top chart indicates the actual number of people for each segment duration as reference. Note that y-axes are at different scales and x-axes are in logarithmic scale. When compatible with the system, the results are reported with inference in GPU (solid lines) and CPU (dashed lines). KEY: #, number of. Trackers (A3–4) obtain lower TCOE than detectors (A1–2). The lowest TCOE is obtained when a reduced number of frames is used as input (e.g., with Systems 3 and 4, or Systems 2 with CPU)
