BRAIN TUMOR IMAGE REGION SEGMENTATION METHOD AND DEVICE, NEURAL NETWORK AND ELECTRONIC EQUIPMENT

Disclosed is a brain tumor image region segmentation method and device, a neural network and electronic equipment. The method includes: acquiring a brain MRI image; building coding modules, wherein each of the coding modules includes coding blocks and an attention model; the MRI image is inputted into the coding blocks to obtain. a first feature map; the attention. model includes a feature attention submodel and a spatial attention submodel which are connected in sequence; the first feature map is inputted into the feature attention submodel to obtain a second feature map; the spatial attention submodel is configured to input the second feature map into the first network and the second network respectively; inputting the brain MRI image into the coding modules, and extracting to obtain a third feature map of the brain MRI image; and decoding the third feature map to obtain a segmented region of the brain tumor.
