SYSTEM AND METHOD FOR EXTRACTING PHYSIOLOGICAL INFORMATION FROM REMOTELY DETECTED ELECTROMAGNETIC RADIATION

摘要

The present invention relates to a system and a related method for extracting physiological information from remotely detected electromagnetic radiation (18, 18a). The system comprises an interface (28) configured for receiving a data stream (26) comprising image data representing an observed overall region (54) comprising at least one subject of interest (12); a partitioning unit (32) configured for defining a plurality of sub regions (62) in the overall region (54); and a classifier (36) configured for classifying the plurality of sub regions (62) into at least one indicative type of region and at least one auxiliary type of region, wherein the at least one indicative type of region comprises at least one indicative region of interest (68) at least partially representing the subject of interest. Preferably, the at least one auxiliary type of region comprises at least one reference region (70, 72, 74). More preferably, the system further comprises a data processor (40) configured for processing at least one sub region (62) classified as region of interest (68), thereby obtaining vital information.
