  1. Errors (mean ± standard deviation) and Pearson’s linear correlation coefficient between true and estimated values for non-degraded simulated images of the cell cluster dataset (N = 1000) are shown for each parameter. Normalized errors were obtained by dividing the errors by the full range of true values. The normalized error and linear correlation coefficient are not applicable to the mean orientation. Mean orientation error is given as absolute error in degrees
