Abstract
The present invention relates to a device, system and method for determining respiratory information of a subject. The device comprises an image input () configured to obtain thermal images of the subject, processing unit () configured to determine respiratory information of the subject from the thermal images, and an output () configured to output the determined respiratory information of the subject. The processing unit () is configured to determine the respiratory information of the subject by identifying in the obtained thermal images respiratory pixels and/or pixel groups that show temperature variations related to respiration, determining, from among the respiratory pixels and/or pixel groups, respiratory flow pixels and/or pixel groups that show respiratory flow, wherein one or more spatial filters are applied to the respiratory pixels and/or pixel groups to discriminate the respiratory flow pixels and/or pixel groups from respiratory motion pixels and/or pixel groups that show respiratory motion, and determining respiratory information of the subject from the respiratory flow pixels and/or pixel groups and/or the respiratory motion pixels and/or pixel groups.
