Fig. 7From: A simplified nonlinear regression method for human height estimation in video surveillanceHeight estimation results for the ruler-based evaluation. a The distribution of estimated height errors. The mean absolute error and the standard deviation of error are 0.42 and 0.54 cm, respectively. b Limits of agreement. The mean difference is −0.10 cm, and the ±1.96 standard deviations are 1.25 and −0.98 cmBack to article page
