数字同轴全息显微镜是一种二维成像技术,最近已被应用于三维成像,然而在三维图像生成的过程中,物体的失焦图像成为三维体积重建上获取明显三维特征的重要障碍。将压缩感知层析重建算法与去卷积算法相结合,显著减少重建中散斑噪声和失焦... 数字同轴全息显微镜是一种二维成像技术,最近已被应用于三维成像,然而在三维图像生成的过程中,物体的失焦图像成为三维体积重建上获取明显三维特征的重要障碍。将压缩感知层析重建算法与去卷积算法相结合,显著减少重建中散斑噪声和失焦伪影对目标的影响。结果显示,与单一的三维去卷积重建图像相比,对于重叠的金属丝,光学标尺,生物棉花切片以及微米级聚苯乙烯颗粒的三维堆积图像具有更好的聚焦效果。 展开更多

The metaverse is a new type of Internet application and social form that integrates a variety of new technologies,including artificial intelligence,digital twins,block chain,cloud computing,virtual reality,robots,with brain-computer interfaces,and 5G.Media convergence technology is a systematic and comprehensive discipline that applies the theories and methods of modern science and technology to the development of media innovation,mainly including multimedia creation,production,communication,service,consumption,reproduction and so on.The emergence of new technologies,such as deep learning,distributed computing,and extended reality has promoted the development of media integration in the metaverse,and these technologies are the key factors that promote the current transformation of the Internet to the metaverse. 展开更多
