We investigate the use of human metrology for the prediction of certain soft biometrics, viz. gender and weight.
In particular, we consider geometric measurements from
the head, and those from the remaining parts of the human
body, and analyze their potential in predicting gender and
weight. For gender prediction, the proposed model results
in a 0.7% misclassification rate using both body and head
information, 1.0% using only body information, and 12.2%
using only head information on the CAESAR 1D database
consisting of 2,369 subjects. For weight prediction, the proposed model gives 0.01 mean absolute error (in the range
0 to 1) using both body and head information, 0.01 using
only body information, and 0.07 using only measurements
from the head. This leads to the observation that human
body metrology contains enough information for reliable
prediction of gender and weight. Furthermore, we investigate the efficacy of the model in practical applications,
where metrology data may be missing or severely contaminated by various sources of noises. The proposed copulabased technique is observed to reduce the impact of noise
on prediction performance
