This
paper proposes a novel feature set for drivers’ stress level recognition. The
proposed feature set consists of data-independent and almost uncorrelated feature
pairs for each stress level with very strong intra-class and relatively weak
inter-class correlations, constructed by realizing a correlation analysis on
the popular features studied in the literature. By using the proposed feature
set, a maximum of 100% stress level recognition accuracy is achieved with an
average increment of 24.85% while a mean reduction rate of 88.01% is satisfied
in false positive rate compared to the full feature set. These outcomes clearly
show that the proposed feature set can confidently be integrated into the
driving assistance systems.
