Animal Eye Blink Detection Based on Frame Subtraction Method

Abstract

In this paper, we propose an animal blink detection method using the frame subtraction method for the purpose of automating physical examination by measuring the blink frequency in a veterinary hospital. The proposed method is based on an algorithm that focuses on the features of the frame subtraction images and is robust to the luminance changes caused by the animal’s body movements. In addition, the proposed system does not require any pre-learning and runs in real-time. For evaluation, we conducted a blink detection experiment using free videos of birds available to the public. Experimental results suggest that the proposed method can be used as a practical blink detector for animals.
