In ghost imaging, an illumination light is split into test and reference beams which pass through two different optical systems respectively and an image is constructed with the second-order correlation between the two light beams. Since both light bea

在地形条件复杂的地区,量化根系对土壤有机碳的贡献对科学评价水土流失区的土壤碳储量具有重要意义.本研究在黄土高原丘陵沟壑区的砖窑沟小流域内,基于地貌类型(梁峁坡、沟坡和沟谷)和植被措施(农田、林地和草地措施)两大因素采集土壤和根系样品,在流域尺度上研究根系密度(FRD)对土壤有机碳密度(SOCD)的贡献.在砖窑沟小流域内,地形、植被措施和土层厚度及其交互作用显著影响SOCD和FRD的空间分布. SO
Diminishing the appearance of a fence in an image is a challenging research area due to the characteristics of fences(thinness, lack of texture, etc.) and the need for occluded background restoration.
2019年6月5日,作为我国首次海上发射的主要"乘客",捕风一号A、B卫星直奔天际,它们将通过一双"慧眼",准确测量海面风场信息,从而实现预报台风。捕风一号A、B卫星的成功发射,将实现我国卫星导航信号探测海面风场零的突破,对我国台风预警、防灾减灾具有重要意义。捕风一号A、B卫星由航天东方红卫星有限公司(以下简称航天东方红)抓总研制。
Ocean vector acoustic measurement is feasible affected by the hydrodynamic interference caused by the flow fluctuations and structural vibrations, especially in the very-low-frequency monitoring. Henc
In this paper, a cardinality compensation method based on Information-weighted Consensus Filter(ICF) using data clustering is proposed in order to accurately estimate the cardinality of the Cardinaliz
Images/videos captured in low-light conditions often present low luminance and contrast.Although the existing low-light enhancement algorithms can improve the subjective perception, color distortion a

With the development of Chinas high-resolution special projects and the rapid development of commercial satellite, the resolution of the mainstream satellite remote sensing images has reached the sub-
数字动画作为新兴的媒体艺术,不免存在一些有待弥补的短板。为此,"对分"演示模式在近两年来成为专业研究领域的热门话题,深得众多媒介工作者的认可并广泛应用,取得了显著效果。本文为探究"对分"应用于数字动画制作中的可行性,重点从两者的特征及结合可行性上进行分析与论述。
随着现代体育不断发展,奥运会承办比赛种类越来越繁杂,对赛事视频分类提出了一个新的挑战。现有的人工分类方法无法有效地区分团体竞技类比赛(球类)和个人竞技类比赛(田径类)视频,从而进行大规模自动分类存储。然而,为了有效地重复使用这些视频文件,需要对其进行分类存储,主要目的在于提高资源的利用率。针对人工分类手段太过于低效的现状,本文对奥运会运动视屏内容分类问题进行研究,并提出了一种基于关键帧特征提取和支
