Context. The article is devoted to the problem of a training data set forming for the automatic human emotions recognition
system on the basis of a multidimensional extended neo-fuzzy neuron. The aspects of choice the attributes vector’s dimension and
composition, their influence on the system learning rate are considered. The object of research is the method of multidimensional
data clustering. The subject of research is two-dimensional images geometric features systematization.
Objective. The main goal of the work is to develop an approach to person’s face expression description using geometric features
fixed set that can be obtained by video sequence frames processing.
Method. To study the facial expressions recognition system it is proposed to form a feature vector consisting of characteristic
points coordinates. There were selected points that relate to the location and shape of the eyelids, eyebrows, eye pupils, lips contours,
nose wings, nasolabial folds. Such points can be easily found during the automatic image processing using known contour detectors.
Also, the possibility of using for the human facial expression description not the coordinates of characteristic points, but the distances
between them, was investigated. From these distances a different feature vector was created, the properties of which were compared
with the points coordinates vector.
Results. The developed recognition system on the basis of a multidimensional extended neo-fuzzy neuron have been
implemented in software and investigated for solving the problem of facial expression classification. A comparison between the
attribute vectors that are different in composition and dimension is made. The structure for the feature vector, which provides high
system learning rate, and does not require the additional structural elements was chosen.
Conclusions. The experimental study fully confirms the effectiveness of the developed approach for the human facial
expressions recognition using a multidimensional extended neo-fuzzy neuron.
