Table 1 Results of the first kind of simulation conducted using the first 400 synthetic bead samples: the percentage errors \(E_{{N\_{\text{DFT}}}}\) and \(E_{{v\_{\text{DFT}}}}\) of the total number \(N_{\text{DFT}}\) and the average speed \(v_{{\text{ave}}\_{\text{DFT}}}\) of a group of synthetic beads due to their Gaussian speed distributions set at four different standard deviations \(\delta_{\text{set}}\)

From: A collective tracking method for preliminary sperm analysis
