Eye movement is one of important index for sleep study. However, it is difficult to measure eye movement and brain function with functional magnetic resonance imaging simultaneously, for investigating the relationship between eye movement and brain function during sleep. We previously proposed a method to measure eye movement from video images that taken during sleeping. This method was based on estimating intensity profile by artificial neural network (ANN). However, this method requires manual detection of eye position from several infrared video images to train ANN. In this paper, we propose a method for estimating visual axes during eye closure. First, we define the visual axes from MR images to train ANN. Next, we estimate visual axes from given infrared video images by estimating intensity profile using the trained ANN. To demonstrate the performance of training the ANN method was applied to a subject. The experimental results showed that the proposed method can detect visual axes from given images with high accuracy. |
