This paper presents a facial expression recognition

approach to recognize the affective states. Feature extraction is

a vital step in the recognition of facial expressions. In this work,

a novel facial ...

In this study, a novel approach is proposed for

mental stress recognition through automatic analysis of eye

video sequences. The proposed system consists of five stages:

video capturing, fuzzy image ...

In this paper, a hybrid approach for the pupil

diameter (PD) measurement from the eye video is described. The

proposed algorithm is composed of five main stages; data

acquisition, pre-processing, edge ...

This paper proposes a fuzzy-based algorithm for measurement of the pupil diameter (PD) from the pupil video.The proposed algorithm consists of fourstages: data
