摘要：
Drowsiness mental state analysis is performed using blink rate. Video is obtained of an individual or group. The individual or group can be within a vehicle. The video is analyzed to detect a blink event based on a classifier, where the blink event is determined by identifying that eyes are closed for a frame in the video. A blink duration is evaluated for the blink event. Blink-rate information is determined using the blink event and one or more other blink events. The evaluating can include evaluating blinking for a group of people. The blink-rate information is compensated to determine drowsiness, based on the temporal distribution mapping of the blink-rate information. Mental states of the individual are inferred for the blink event based on the blink event, the blink duration of the individual, and the blink-rate information that was compensated. The compensating is biased based on demographic information of the individual.
