This paper presents a video processing framework developed in order to analyze eye and eyelid movements of impaired people. In the case of physically impaired individuals eye and eyelid movements may represent the only effective communication method that they could use to interact. Video processing algorithms are involved in the framework that we propose to aid people in this situation. A high speed...
The paper presents a high speed video processing algorithm designed to measure several parameters related to eyelid movements during blinking. First, the facial features of the subject are detected and tracked; then, the eye regions of interest are extracted using data regarding face orientation and eyebrows position. In the next stage, eye contour and representative lines for upper and lower eyelids...
The paper presents an algorithm designed to face and facial features (eyes, eyebrows) detection. First, human skin regions are segmented and processed by morphological operators to detect the human face. After the face has been detected, a series of parameters that will be taken into account by the eyes detection stage are calculated. The most important parameters are face orientation and distance...
This paper presents an image processing algorithm designed to measure eyelid movements during blinking. First, the facial features of the subject are detected and tracked; then, the eye regions of interest are extracted using information regarding face orientation and eyelids position. In the next stage, the eyelid line is detected from the image, after which the eyelid characteristics are extracted...
