| description | The invention discloses a method and system for segmenting choroidal neovascularization in an optical coherence tomography image, and the method comprises the steps: constructing a UNet-based segmentation network, setting two paths during down-sampling, and respectively extracting multi-scale global features and multi-scale global features with local semantic information and long-distance dependence information; the features extracted on the two paths are fused, and the fused features of each scale are output, so that feature information can be fully extracted; in the up-sampling process, the fused features and the up-sampling features of the same scale are enhanced and then fused, generation of lesion features in the up-sampling process can be more focused, lesion boundary information in the up-sampling process is made to serve as supervision information to enhance expression of boundary information, fine segmentation can be carried out, and the segmentation effect is improved.
