[0036] The implementation of the sparse representation-based classification and recognition method of newborn pain and non-pain expressions of the present invention mainly includes the following steps:
[0037] Step 1: Build a library of newborn facial expression images
[0038] In the process of routine pain-causing operations (such as vaccination, blood sampling) for newborns and premature infants, digital cameras are used to take facial images of newborns. Specially trained doctors and nurses use the internationally recognized neonatal pain assessment tool—Neonatal Facial Coding System (NFCS), combined with other physiological indicators, to perform the analysis on the collected neonatal facial images. For the evaluation of pain degree, a score from 1 to 10 is given according to the degree of pain. Expressions with a score of 1 to 5 are classified as mild pain expressions, and those with a score of 6 to 10 are classified as severe pain expressions . In addition, the non-pain e...
