1. A method for performing medical image segmentation, the method comprising:
obtaining, by a device comprising a memory storing instructions and a processor in communication with the memory, a first medical image and a second medical image with a labeled region;
performing, by the device, feature extraction on the first medical image and the second medical image respectively, to obtain first feature information of the first medical image and second feature information of the second medical image;
obtaining, by the device, optical flow motion information from the second medical image to the first medical image according to the first feature information and the second feature information by:
associating, by the device, the first feature information with the second feature information, to obtain pixel position correspondence information between the second medical image and the first medical image, and
performing, by the device, an upsampling operation on the pixel position correspondence information, to obtain the optical flow motion information from the second medical image to the first medical image; and

segmenting, by the device, the first medical image according to the optical flow motion information and the labeled region, to obtain a segmentation result of the first medical image.
