Title: An efficient method for detection of inspiration phase of respiration in thermal imaging
Authors: Deepika, C L; Kandaswamy, A; Pradeepa, G
Abstract: Respiration rate and the time duration between successive respiration
cycles are two important parameters required for detection of apnea disorders
during a polysomnograph test. Conventional methods use thermistors and
respiration belts to measure these parameters. These however cause patient
discomfort and also tether the patient to the bed. Thermal imaging is proposed
in literature for non-contact measurement of respiration rate, wherein the
inspiration and expiration of the patient can be visually monitored as
temperature variations from his thermal images. In this paper, a segmentation
approach is proposed to accurately localize the low temperature region that
occurs near the nostrils during inhalation.
