摘要：
Mental state analysis is performed using blink rate within vehicles. Video is obtained of an individual or a group 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 using the processors for a context. Mental states of the individual are inferred for the blink event, where the mental states are based on the blink event, the blink duration of the individual, and the blink-rate information that was compensated. A difference in blinking between the individual and the remainder of a group can be determined.
