Table 1.

C_EST is the average estimated count. The ground truth counts were 25.71 for cells and 8.19 for lesions. MAE is the mean absolute error, ± standard deviation. ρ is the correlation coefficient between estimated and ground truth counts. f is the fraction of the ground truth points within the bounds and W is the mean width of the intervals—evaluated on both uncalibrated and calibrated intervals.
