Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
acquiring 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;
performing image segmentation processing based on a plurality of sub-images of the first image to obtain a first initial segmentation result, comprising:
identifying a plurality of edge sub-images that include an edge of the imaging target from among the plurality of sub-images;
performing 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;
identifying a plurality of non-edge sub-images that do not include an edge of the imaging target from among the plurality of sub-images;
determining 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
obtaining the first initial segmentation result based on the plurality of sub-segmentation results, comprising:
stitching 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;

performing image segmentation processing based on the second image to obtain a second initial segmentation result;
merging, based on the imaging target, the first initial segmentation result with the second initial segmentation result to obtain a target segmentation result; and
outputting or storing the target segment result.
