Abstract
A method for determining human eye close degrees includes: acquiring a face image; determining a human eye open amplitude and a reference distance in the face image; calculating a relative amplitude of the human eye open amplitude relative to the reference distance; acquiring a maximum relative amplitude; and calculating a human eye close weight in the face image based on the relative amplitude and the maximum relative amplitude, the human eye close weight being configured to measure a human eye close degree.
