Video based non-contact monitoring of respiratory rate and chest indrawing in children with pneumonia
Objective. Pneumonia is the single largest cause of death in children worldwide due to infectious
diseases. According to WHO guidelines, fast breathing and chest indrawing are the key indicators of
pneumonia in children requiring antibiotic treatments. The aim of this study was to develop a video
based novel method for simultaneous monitoring of respiratory rate and chest indrawing without
upsetting babies. Approach. Respiratory signals, corresponding to periodic movements of
chest-abdominal walls during breathing, were extracted by analyzing RGB (red, green, blue)
components in video frames captured by a smartphone camera. Respiratory rate was then obtained by
applying fast Fourier transform on the de-noised respiratory signal. Chest indrawing was detected by
analysing relative phases of regional chest-abdominal wall mobility. The performance of the
developed algorithm was evaluated on both healthy and pneumonia children. Main results. The proposed
method ...
