## Abstract (arXiv)

The facial expression recognition is an ocular task that can be performed without human discomfort, is really a speedily growing on the computer research field.

The process of recognizing facial expression is a hard task due to the several circumstances such as facial occlusions, face shape, illumination, face colors, and etc. This paper present a PCA methodology to distinguish expressions of faces under different circumstances and identifying it.
