Classification: CPC G | IPC G

Claim 4:
5. An apparatus for performing medical image segmentation, the apparatus comprising:
a memory storing instructions; and
a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform:
obtaining a first medical image and a second medical image with a labeled region,
performing 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 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 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 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 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.
