FaceReader is as good at recognizing facial expressions as humans.
In this study the FaceReader software was validated on two publicly available and objective datasets of human
expressions of basic emotion (WSEFEP & ADFES). Facereader categorized 88% of the emotions
accurately, which is similar to the human recognition scores (average of 85%). The table on the
right shows the accuracy scores for each of the basic emotions.
Facereader even outperforms
humans when categorising neutral faces, reducing a possible bias in the analysis. This study
also indicated that action units from the Facial Action Coding System (FACS) can also be used
with high accuracy (in the future action units will also be available in FaceReaderOnline).
