Embodiment Construction
[0046] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0047] The present invention provides a newborn pain expression recognition method based on dual-channel feature deep learning, such as figure 1 As shown, the specific steps are as follows:
[0048] A. Newborn facial images were collected, and professional medical staff classified them into n types of expressions according to the degree of pain, and a newborn facial expression image database was established.
[0049] B, The sample in the neonatal facial expression image library is preprocessed by cropping, alignment, and scale normalization to obtain an image with a size of l×l pixels.
[0050] C, the preprocessed neonatal facial expression image is grayscaled, and its local binary pattern (Local Binary Pattern, LBP) feature map is extracted.
[0051] D, Constructing a dual-channel convolutional neural network for deep learning of the image featu...
