二维视频三维化的新方法

基于3DsMAX软件平台,根据对二维视频中帧间物体与摄像机位置关系和现有的二维视频转三维的方法的分析,提出了一种二维视频转化成3DTV的新思路--利用视频帧间本身具有的三维视差信息对运动物体进行图像处理后所得图像作为视差图,同时运用三维合图程序得到用于显示的合成图,并对其可行性作了理论和实验t的比较分析,实验证明该方法在某些特定环境中的可操作性,比较了与其他三维化方法的优劣.

A Case study of a snowstorm at the Great Wall Station,Antarctica

A case of a snowstorm at the Great Wall Station was studied using data of NCEP (National Centers for Environmental Prediction) analysis, in situ observations and surface weather charts. The storm occurred on August 29th,2006, and brought high winds and poor horizontal visibility to the region.It was found that the storm occurred under the synoptic situation of a high in the south and a low in the north. A low-level easterly jet from the Antarctic continent significantly decreased the air temperature and humidity.Warm air advection at high level brought sufficient vapor from lower latitudes for the snowstorm to develop.The dynamic factors relating to strong snowfall and even the developmentof a snowstorm were deep cyclonic vorticity at middle and low levels,the configuration of divergence at high level and convergence at low level, and strong verticaluplift. There was an inversion layer in the low-level atmosphere during the later phase of the storm.This vertical structure of cold air at low levels and warm air at high levels may have been important to the longevity of the snowstorm.     

Occurrence and Diversity of Candida Genus in Marine Environments

A total of 317 yeast isolates from seawater,sediments,mud of salterns,guts of marine fishes and marine algae wereobtained.The results of routine identification and molecular characterization showed that six isolates among these marine yeastsbelonged to Candida genus as Candida interrnedia for YA01a,Candida parapsilosis for 3eA2,Candida quercitrusa for JHSb,Can-die rugosa for wl8,Candida zeylanoides for TJY13a,and Candida membranifaciens for W14-3.Isolates YA01a (Candida interme-die),wl8 (Candida rugosa),3eA2 (Candida parapsilosis),and JHSb (Candida quercitrusa) were found producing cell-bound lipase,while isolate W14-3 (Candida membranifaciens) producing riboflavin.These marine yeast Candida spp.Seem to have wide potentialapplications in biotechnology.     

21世纪初期河南省基础地质研究方向与成功战略

20世纪河南省基础地质研究经历三个阶段。第一阶段50年,随矿产调查进行。第二阶段30年,随矿产勘查和1∶20万区调开展。第三阶段20年,随1∶5万区调、矿产勘查、专题与综合研究广泛展开。为谋求21世纪初期河南省基础地质较快发展,作者认为应有新的指导思想、研究方法和服务方向,并提出知识创新、人才培养和经费保障三项成功战略。     

近20年来福州市土地利用时空变化的遥感分析

以1986、1996和2006年三期Landsat TM影像为基本数据源,采用最大似然法分类,并以同期高分辨率的SPOT5影像进行分类后处理,最后分类后变化检测法监测了福州市1986~2006年的土地利用变化及其转移模式。结果表明,福州市近20年间土地利用发生了较大的变化,城乡建筑用地处于快速增长阶段,而耕地数量却在不断下降。经济发展、人口增长、政府决策等因素是福州市土地利用发生变化的主要驱动力。
