Receiver functions(RFs)obtained using teleseismic wave records at a seismic station and synthetic seismograms indicate that RF with a single teleseismic wave record is related to the selection of reco
The 12 May 2008 Wenchuan Ms8.0 earthquake produced surface displacements along the causative fault,the Yingxiu-Beichuan Fault,which are up to several meters near the fault.Because of the large gradien
为促进铁路站车人脸识别系统的建设与发展,加快相关技术规范和标准的制定,铁路站车人脸识别系统专题研讨会2012年3月2日在京召开。会议由中国铁道科学研究院电子计算技术研究所主办,《中国铁路》编辑部承办。会议特邀请铁道部信息办、公安局、运输局电务部、科技司、鉴定中心相关领导莅临会议。北京、上海、天
多帧图像超分辨率重建中,连续各帧图像间的精确匹配和帧的选择具有非常重要的意义。提出了自适应帧选择原则,设计了联合光子流运动估计配准和超分辨率重建的方法。首先采用光子流运动估计算法计算各帧间的运动估计,设计一种自适应帧选择方法丢弃一些帧间运动较大的帧,再通过亚像素图像配准,计算得到相对精确的运动估计参数,最后结合最大后延概率方法进行图像超分辨率计算,并充分考虑两次迭代所得图像向量的差值对下次迭代算法

Three-dimensional (3-D) video applications,such as 3-D cinema,3DTV,and Free Viewpoint Video (FVV) are attracting more attention both from the industry and in the literature.High accuracy of depth vide
A method was developed to detect generic objects using a single query image.The query image could be a typical real image,a virtual image,or even a hand-drawn sketch of the object.Without a training p
[目的]研究水稻监控系统中的数字图像压缩技术。[方法]提出了一种基于离散傅立叶变换的数字图像压缩技术方案,并通过仿真试验对图像进行了不同压缩比的压缩。[结果]对于压缩比在30以内的数字图像的压缩,衡量编码压缩质量的5个参数(压缩比、图像的熵、平均码字长度、编码效率、冗余度)和评价压缩图像逼真度的参数(PSNR)均达到较好效果,人眼几乎不能分辨出解压缩图像和原始图像之间的差异;在压缩比超过30的数字
