Abstract Purpose Automatic segmentation of brain tumors by deep learning algorithm is one of the research hotspots in the field of medical image segmentation. An improved FPN network for brain tumor segmentation is proposed to improve the segmentation effect of brain tumor. Materials and methods Aiming at the problem that the traditional full convolutional neural network (FCN) has wea... https://www.espumasyterciopelo.com/product-category/balloon-decor/
