Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A system, comprising:
a processor; and
a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:
acquire a first image and a second image, wherein the first image and the second image are acquired based on a same imaging target, and wherein a resolution of the first image is greater than a resolution of the second image;
perform image segmentation processing based on a plurality of sub-images of the first image to obtain a first initial segmentation result, comprising to:
identify a plurality of edge sub-images that include an edge of the imaging target from among the plurality of sub-images;
perform image segmentation processing on the plurality of edge sub-images using a pre-trained segmentation neural network to obtain a plurality of sub-segmentation results individually corresponding to the plurality of edge sub-images;
identify a plurality of non-edge sub-images that do not include an edge of the imaging target from among the plurality of sub-images;
determine a plurality of sub-segmentation results corresponding to the plurality of non-edge sub-images based on image content included in the plurality of non-edge sub-images; and
obtain the first initial segmentation result based on the plurality of sub-segmentation results, comprising to:
stitch together the plurality of sub-segmentation results of the plurality of edge sub-images with the plurality of sub-segmentation results of the plurality of non-edge sub-images to obtain the first initial segmentation result;

perform image segmentation processing based on the second image to obtain a second initial segmentation result; and
merge, based on the imaging target, the first initial segmentation result with the second initial segmentation result to obtain a target segmentation result; and
output or store the target segment result.
