Embodiment Construction
[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0030] figure 1 It is a system frame diagram of a neural network-based symmetric brain tumor segmentation method of the present invention. It mainly includes encoding neural networks, datasets, preprocessing, and model comparison.
[0031] Among them, the symmetric encoding neural network first calculates the difference between the original brain image and the flipped brain image, extracts features on the difference, connects the difference with the feature map of the original image to preserve the information of the original image, and then performs a Symmetry is encoded in the network; since brain symmetry is at a high level of abstraction, performing subtraction on the symmetry aft...
