A Comprehensive Study of Major Techniques of Facial Expression Recognition
نویسندگان
چکیده
Facial Expression Recognition is one of the challenging and active research topic in the recent years. Facial Expression Recognition System comprises the detection of face, facial feature extraction and classification of facial expression from still images. This paper summarizes the major techniques to recognize the facial expressions from still images. The techniques included in this paper are Principal Component Analysis, Singular Value Decomposition, Neural Network, Cloud Model, Fuzzy Model and K-Means Clustering Algorithm. The performance of these techniques is good enough and almost effective also except fuzzy model. Fuzzy model does not classify the expressions exactly. The main purpose of this research work is to present the major techniques of automatic facial expression recognition in a single view.

A comprehensive experimental comparison of the aggregation techniques for face recognition
In face recognition, one of the most important problems to tackle is a large amount of data and the redundancy of information contained in facial images. There are numerous approaches attempting to reduce this redundancy. One of them is information aggregation based on the results of classifiers built on selected facial areas being the most salient regions from the point of view of classificati...
