Dianci bileiqi, 2022 传统方法在进行±1 100 kV输电线路复合绝缘子缺陷多源特征及模式识别时，去噪效果不佳，无法提取准确的缺陷特征，模式识别用时较长。为此，提出一种新的方法解决以上问题。对输电线路复合绝缘子图像进行均衡化处理，实现图像增强；采用均值滤波方法实现图像去噪，并在二维熵的基础上完成图像分割。提取直线特征、斑点特征和分块统计特征构建复合绝缘子缺陷的特征集，应用BPSO算法融合直线特征、斑点特征与分块统计特征，获得复合绝缘子缺陷特征，构建输电线路复合绝缘子缺陷模式识别模型，实现复合绝缘子缺陷特征及模式的识别 ...

Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT AI‐generated images have become so good in recent years that individuals often cannot distinguish them from ‘real’ images. This development, combined with the rapid spread of AI‐generated content online, creates a series of societal risks. Watermarking, a technique that involves embedding information within the content to indicate their AI ...
