Figure 2. Tracking performance.

The ground truth data from the work of Chenouard et al. were compared to the tracking results produced using Diatrack¹⁹. As described in Chenouard et al., Alpha is a measure of track quality, while RMSE represents the root mean square discrepancy between true positions of particles and those corresponding positions found using Diatrack. The software performed really well, especially in light of the fact that it was not modified or tuned for the purpose of dealing with these particular data sets. It was also very fast in 2D (last row). Additional results may be found in the supplementary information.
