Claim:
1. A computer-implemented method for mental state analysis comprising: obtaining video of an individual; analyzing, using one or more processors, the video to detect a blink event based on a classifier for a blink that was determined wherein the blink event is determined by: locating a portion of a face with eyes; performing temporal analysis on the portion of the face; and identifying that the eyes are closed for a frame in the video using the temporal analysis; evaluating a blink duration of the individual for the blink event; determining blink-rate information using the blink event and one or more other blink events; compensating the blink-rate information for a context; evaluating blinking for a group of people of which the individual is a part; evaluating an average blink duration for the group of people; determining a difference in blinking between the individual and a remainder of the group; and inferring mental states of the individual for the blink event, wherein the mental states are based on the blink event, the blink duration of the individual, the average blink duration for the group of people, and the blink-rate information that was compensated.
