Abstract

The embodiment of the invention provides a segmentation method and device for a target object in a three-dimensional image and electronic equipment. The method comprises the following steps: accordingto a plurality of branch feature three-dimensional networks of a multi-channel three-dimensional network model, respectively carrying out feature extraction on three-dimensional images of a pluralityof modal groups to be segmented to obtain branch feature maps of a plurality of branches; according to the fusion feature three-dimensional network, performing feature extraction and fusion on the branch feature maps of the plurality of branches to obtain a fusion feature map; and according to the size amplification three-dimensional network, performing fusion and size amplification on the fusionfeature map and the branch feature maps of the plurality of branches to obtain a three-dimensional image of the segmented target object. In the embodiment of the invention, different morphological characteristics of the same target object in the three-dimensional images of different modal groups are extracted and fused, and the type and edge recognition precision of the target object is greatly improved, so that the segmentation precision of the target object is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present invention relates to a method, device and electronic equipment for segmenting a target object in a three-dimensional image. Background technique [0002] Currently, there are some three-dimensional images, including medical three-dimensional images, for example, CT (Computed Tomography, computerized tomography) images and MRI (nuclear Magnetic Resonance Imaging, nuclear magnetic resonance imaging) images. It is difficult for users to visually identify each target object from a 3D image. For example, it is difficult for a doctor to screen and identify target objects one by one from a medical 3D image, which is prone to false detection and missed detection, and is time-consuming. Therefore, related art personnel have developed methods for segmenting target objects in 3D images. [0003] In the prior art, there is a target object segmentation method...
