On an image processing of eye blinking to monitor awakening levels of human beings

The main goal of the present study was to design and examine a system to monitor awakening levels of human beings using the image processing technique to recognize eye blinking. This problem was divided into two sub-problems; to obtain images by decreasing noise and simplify the images, and to detect whether eyes were closed or opened. A filtering technique and the automatic threshold determination method were used to solve the former sub-problem and the automatic detection system was designed for the latter sub-problem. To examine the reliability of the designed system, a comparison between the result detected by the system and that detected by a sensor using electroencephalograms (EEGs) was made.
