Reliability comparison with manually tracked ground-truth data between tracking algorithms.

For comparison, only automatically tracked radii below 270 px were used, as this is the maximum radius tracked with the Hough Transform and approximately the maximum radius found manually (max: 266 px). This also applies to smoothed radii. While smoothing increases tracking success for Hough Transform, tracking works equally well, if not better, without smoothing using DLC+ tracking. Notice that these correlations feature the whole subset of data. The Hough Transform works very well for particular examples; DLC+ works better on average and, across the board, has a high performance.
