Embodiment Construction
[0053]The present invention will be further described below in conjunction with the accompanying drawings of the specification.
[0054]Such asfigure 1 As shown, the automatic segmentation method of ultrasonic breast tumor based on Attention-enhancing Unet (AE-Unet) of the present invention includes the following steps:
[0055]Step (A), construct an attention-enhanced U-shaped network model for automatic segmentation of ultrasound breast tumors such asfigure 2 andimage 3 As shown, including the following steps,
[0056](A1) Establish a left-side contraction path. The left-side contraction path includes three arithmetic modules of left convolution, downsampling, and left modified linear unit (Relu). The left convolution arithmetic module is used to extract the deep semantic features of the image. The size of the convolution kernel of all left convolution budget modules is 3*3; after each left convolution operation, the activation function of the left Relu operation module is required to enha...
