BREATHING PATTERN IDENTIFICATION FOR RESPIRATORY FUNCTION ASSESSMENT
First Claim
1. A method for identifying a breathing pattern of a subject for respiratory function assessment in a remote sensing environment, the method comprising:
- receiving a time-varying sequence of depth maps of a target region of a subject of interest being monitored for respiratory function assessment, said depth maps being of said target region over a period of inspiration and expiration;
processing said depth maps to obtain a breathing signal for said subject comprising a temporal sequence of instantaneous volumes across time intervals during inspiratory and expiratory breathing;
comparing at least one segment of said subject'"'"'s breathing signal against a reference breathing signal associated with a known pattern of breathing; and
identifying, as a result of said comparison, a breathing pattern for said subject.

Abstract
What is disclosed is a system and method for identifying a patient'"'"'s breathing pattern for respiratory function assessment without contact and with a depth-capable imaging system. In one embodiment, a time-varying sequence of depth maps are received of a target region of a subject of interest over a period of inspiration and expiration. Once received, the depth maps are processed to obtain a breathing signal for the subject. The subject'"'"'s breathing signal comprises a temporal sequence of instantaneous volumes. One or more segments of the subject'"'"'s breathing signal are then compared against one or more reference breathing signals each associated with a known pattern of breathing. As a result of the comparison, a breathing pattern for the subject is identified. The identified breathing pattern is then used to assess the subject'"'"'s respiratory function. The teachings hereof find their uses in an array of diverse medical applications. Various embodiments are disclosed.
