Claim 1:
2. The method according to claim 1, wherein the cascaded segmentation network further includes a third-level segmentation network, and wherein performing image segmentation on the tumor region in the candidate image using the first-level segmentation network and the second-level segmentation network in the cascaded segmentation network to obtain the segmented image comprises:
performing image segmentation on the candidate image using the first-level segmentation network to obtain a first-level intermediate segmented image marked with the general tumor region;
performing image segmentation on the first-level intermediate segmented image using the second-level segmentation network to obtain a second-level intermediate segmented image marked with the general tumor region and a tumor core region; and
performing image segmentation on the second-level intermediate segmented image using the third-level segmentation network to obtain the segmented image marked with the general tumor region, the tumor core region, and an enhancing tumor core region.
