摘要：
The invention relates to a system for real-time assessment of alertness level in human beings. The system comprising at least one digital camera for capturing the image of a subject in a given time window an embedded processor with a logic rule for receiving, processing the captured image data, and outputting signals representing alertness state classification of the subject a display device for exhibiting the outputted alertness level data from the processor and a device for sounding an alarm when the detected alertness level of the subject is below a threshold value. The system is configured to: localize the face and eye of the subject"s image within the captured image frame register the eye image and transmit to the processor remove glint in the eye image detect the eye corner of the subject"s registered eye image to obtain a reference point compute an iris centre position of the eye determine an iris velocity and decide the alertness level of the subject based on a comparison of the processed data with a pre- stored set of data.
