14. An apparatus for segmenting a medical image, comprising:
a memory operable to store computer-readable instructions; and
a processor operable to read the computer-readable instructions, the processor when executing the computer-readable instructions is configured to:
obtain a slice pair comprising two slices from a medical image;
perform feature extraction on each slice in the slice pair, using different receptive fields, to obtain high-level feature information and low-level feature information of the each slice in the slice pair;
segment a target object in the each slice in the slice pair according to the low-level feature information and the high-level feature information of the each slice, to obtain an initial segmentation result of the each slice;
fuse the low-level feature information and the high-level feature information of the slices in the slice pair to obtain a fused feature information;
determine correlation information between the slices in the slice pair according to the fused feature information; and
generate a segmentation result of the slice pair based on the correlation information and the initial segmentation results of the slices in the slice pair.
