METHOD FOR SENSING SLEEPINESS BY EYE-BLINKING AND METHOD FOR CHASING EYE-AREA DEFORMED IN THE PROCESS OF SLEEPINESS LEVEL DETECTION PREPROCESSING

摘要

PURPOSE: A method for sensing sleepiness by eye-blinking and a method for chasing an eye-area deformed in the process of sleepiness level detection preprocessing are provided to easily detect a sleepiness level under the various circumstances caused by the changes of an original image size and an inclination, and a sudden illumination change, without repeatedly detecting a face area and an eye area for each image. CONSTITUTION: A method for sensing sleepiness by eye-blinking includes the steps of determining an eye position searching area in an input image for detecting eye positions in the eye position searching area by using a template for inspecting characteristics of eyes(310), determining whether the eyes are opened or not by extracting upper and lower border lines of the eyes from the detected eye positions(320), and detecting a sleepiness level indicating a time degree that the eyes are closed by continuously monitoring whether the eyes are opened or not for continuous images(330).
