Abstract

The invention discloses a method for clustering and style migration of ultrasound images, and the method comprises the following steps: 1, carrying out the data preprocessing, and converting the ultrasonic image into a data vector; 2, performing a contrast experiment by using three clustering algorithms: a K-means clustering algorithm, a condensation hierarchical clustering algorithm and a spectral clustering algorithm, and selecting an optimal algorithm; 3, selecting an image with large style difference according to a clustering experiment result; 4, designing a network structure and a loss function based on the CycleGAN; and 5, designing a style migration experiment for the benign and malignant data set, and analyzing an experiment result. According to the clustering and style migrationalgorithm designed by the invention, the influence of noise on an experimental result is effectively avoided, and the adaptability of the used method to noise image data is presented.

Description

technical field [0001] The invention belongs to the technical field of machine learning and image style transfer, and relates to image clustering and style transfer algorithms, in particular to a method for clustering and style transfer of ultrasound images. Background technique [0002] Clustering refers to the process of dividing a group of objects into multiple classes composed of these objects. Unlike classification, clustering does not divide objects into different categories based on known information, but divides them into unknown features. the type. The core idea of ​​the hierarchical-based clustering method is to construct data objects into a tree, each node except the leaf node is composed of the union of its subtrees, and the root node contains all data objects. The process of hierarchical decomposition is generally divided into two categories: agglomeration method, which starts from the leaf node and merges the two closest nodes each time until the node contains...
