Problems solved by technology

[0006] (1) The design of reverse short jump links: In order to alleviate the problem of information loss caused by multiple image downsampling, existing segmentation networks (such as U-Net and BiO-Net) usually use skip links to encode and decode images. The convolutional features are connected in series to ensure that the decoding convolution module has enough information input and learns and captures the required target features from the input information.

Embodiment Construction

[0021] The following is a further description of a loop-jumping deep learning network and its application in conjunction with the accompanying drawings;

[0022] refer to figure 1 , the deep learning network and application of a kind of cyclic jumping of the present invention, comprise the following steps:

[0023]Step 1, analyze the role of skip links in existing segmentation networks (such as U-Net and BiO-Net) and its shortcomings, and then design appropriate skip links and convolution modules to alleviate the loss of image information and improve Segmentation performance of the network. Specifically, existing segmentation networks mainly use forward and reverse skip links to transfer feature information between encoding and decoding convolutional modules, however these skip links can only transfer a single type of feature with the same image dimension to the specified The convolution module thus limits the diverse integration of image information, making it difficult to ...

Abstract

The invention relates to a cyclic hopping deep learning network, which is mainly used for accurately extracting different interested targets in medical images. According to the network, a new reverse short hopping link and an attention-guided convolution module are introduced on the basis of an existing BiO-Net segmentation network, so that a cyclic hopping deep learning network is constructed, and then local OCT image data and public fundus image data are sampled to verify the segmentation performance of the network. According to the invention, different interested targets in the image can be effectively extracted, and the network has segmentation performance superior to that of existing networks such as U-Net, AU-Net and BiO-Net.

Description

technical field [0001] The invention relates to the technical field of image segmentation, in particular to a loop-jumping deep learning network. Background technique [0002] Image segmentation is a process that divides an image into different regions and makes each region have completely different imaging characteristics (such as pixel gray distribution, tissue contrast, and anatomical shape, etc.), thereby reducing the difficulty of analysis and measurement of the region of interest, and providing a basis for the diagnosis and treatment of related diseases. Lesion location and morphological quantification, disease analysis, clinical diagnosis and prognosis monitoring provide key guidance, so it has important academic research value. In order to accurately extract the desired region of interest, a large number of image segmentation algorithms have been developed, such as threshold-based methods, active contour-based methods, and atlas-based methods. These segmentation alg...
