Comparison of ILDref with the depths obtained by four different threshold values.

The mean of paired absolute differences (meanad) and bias (mean difference) are listed with their associated standard error (standard deviation divided by , N = sample size).配对绝对差值均值（meanad，即mean of paired absolute differences）与偏差（bias，即均值差）将与其各自对应的标准误一同列出，其中标准误的计算方式为标准差除以N，N为样本量。
