Comparison of the estimated and actual neurofilament velocities obtained using three different particle tracking algorithms. These data were obtained using the moving neurofilament shown in Fig. 5. The open squares represent the data obtained by using particle filtering and the open circles represent the data obtained by an experienced user using manual tracking. (a) GPF with 200 particles, (b) OCPF with 50 particles, (c) OCPF with 100 particles, and (d) SCPF with 50 particles. Note that there is considerable discrepancy between the actual velocities and the estimated velocities obtained using GPF and OCPF, but good agreement with the estimated velocities obtained using SCPF.
