Newborn-painful-expression recognition method based on dual-channel-characteristic deep learning

Abstract

The invention discloses a newborn-painful-expression recognition method based on dual-channel-characteristic deep learning. The newborn-painful-expression recognition method includes the steps that firstly, newborn facial images are grayed, and a Local Binary Pattern (LBP) specific chromatogram is extracted; secondly, grayscale images of the parallelly-input newborn facial images and the characteristics of two channels of LBP characteristic images of the grayscale images are deeply learned with a dual-channel convolutional neural network; finally, the fusion characteristics of the two channels are subjected to expression classification through a classifier based on a softmax, and expressions are divided into the calmness expression, the crying expression, the mild pain expression and the acute pain expression. According to the newborn-painful-expression recognition method, the grayscale images and the characteristic information of the two channels of the LBP characteristic images of the grayscale images are combined, the expressions such as the calmness expression, the crying expression, the mild pain expression and the acute pain expression can be effectively recognized, the quite-good robustness of the illumination problem, the noise problem and the shielding problem of the newborn facial images is achieved, and a new method and way are provided for developing a newborn-painful-expression recognition system.

Description

technical field [0001] The invention relates to a newborn pain expression recognition method based on dual-channel feature deep learning, which belongs to the field of image processing and emotion recognition. Background technique [0002] Pain is a common uncomfortable symptom of the human body. It not only makes people suffer, but also brings a series of physiological and psychological adverse effects. Studies have shown that newborns have the ability to feel pain after birth, and can transmit, perceive, respond to and even remember harmful stimuli. Various examinations and treatments received from birth will bring pain and stimulation to newborns. Painful stimuli can cause systemic reactions in the body, such as changes in breathing and immunity, and instability of cardiovascular function; this pain may also lead to long-term effects such as developmental delay in newborns, permanent damage to the central nervous system, and emotional disorders. Early repeated operant p...
