Towards Automated Three-Dimensional Tracking of Nephrons through Stacked Histological Image Sets

Table 2

Test results on a chosen set of 16 mouse nephrons and 11 rat nephrons. The number of manual corrections is given as the mean ± one standard deviation. Ideal values for the six segments for both the mouse and rat were derived from measurement of manual data and the results in the appendix of the previous study [8].
