Abstract :
This paper presents a vision-based infant-pain monitoring system that adopts an infant behavior analysis approach to detect infant injuries. In our study, the system first pre-processes the input sequence to filter out the noise and reduce the effects of lights and shadows. Then, the infant´s faces are detected from the input frames and feature extraction was done with SVD and FFT. A k-NN classifier was employed to describe pain over time. It is found that the identification rate of reaches 83.12%.
