Abstract

In this paper, a novel drowsiness detection algorithm using eye-blink pattern is proposed. The proposed drowsiness detection model using finite automata makes it easy to detect eye-blink, drowsiness and sleep by checking the number of input symbols standing for closed eye state only. Also it increases the accuracy by taking vertical projection histogram after locating the eye region using the feature of horizontal projection histogram, and minimizes the external effects such as eyebrows or black-framed glasses. Experimental results in eye-blinks detection using the JZU eye-blink database show that our approach achieves more than 93% precision and high performance.

본 논문은 눈 깜박임 패턴을 이용한 새로운 졸음 검출 알고리즘을 제안하였다. 유한오토마타를 이용한 졸음 검출 모델을 제안하여 눈감은 상태를 나타내는 입력 심벌의 개수만을 체크함으로써 눈 깜박임, 졸음, 수면 검출을 용이하게 하였다. 또한 수평 투영 히스토그램의 특성을 이용하여 눈동자가 있는 영역만을 구해 수직 투영 히스토그램을 취함으로써 눈썹이나 안경테와 같은 외부 영향을 최소화 시켜 정확도를 높였다. ZJU 눈 깜박임 데이터베이스를 이용한 눈 깜박임 검출 실험 결과 93% 이상의 정확도를 얻음으로써 제안된 방법의 우수함을 보였다.
