Claim 9:
10. The method according to claim 9, wherein constructing the cascaded segmentation network based on the machine learning model comprises:
obtaining training samples carrying labels, wherein the training samples are tumor images on which the general tumor region, the tumor core region, and the enhancing tumor core region are labeled with different types of labels;
establishing a plurality of training sample sets according to types of the labels carried by the training samples, each of the training sample sets corresponding to a type;
performing model training on a plurality of convolutional neural network models having designated model structures respectively by using the plurality of training sample sets; and
cascading the plurality of convolutional neural network models after the model training is performed to obtain the cascaded segmentation network.
