在数字上

The paper is trying to integrate the technique of digital photogrammetry in feature extraction and the theory of intelligent image processing in computer vision, and puts forward and realizes a set of methodizes and algorithm that are valuable for practical production of mapping from space images..

从半自动的提取的人机协同策略到完全自动的道路网解译、从二维信息的提取到直接提取目标的三维模型，本文力图将数字摄影测量对特征提取、精确定位等方面的成果，与计算机视觉领域对图象进行智能解译的理论结合起来，在线状地物与房屋的自动提取方面，在理论与实践上提出并实现了一系列有实际应用价值的方法和算法。

The digital revolution is both necessitating and facilitating radical changes in how and what we learn.

For the typical mutual-fund investor, who holds 12% to 15% in foreign stocks -- or half that in a 401 -- holding 55% in foreign stocks would seem like a massive overweighting toward overseas markets.

典型的共同基金投资者通常会持有12%-15%的外国股票，或在401计划中持有这个数字一半的外国股票。对他们而言，将55%的资金放在外国股票上似乎是太高了。

In order to extend the effect and security of image encryption algorithm.An image encryption algorithm is presented based on three-dimension chaotic system and bit-computation.The permutation sequences and binary sequences are generated using three-dimension chaotic system.Firstly,the image is pretreated using chaotic system and permutation transformation,then the pixel's gray value's bit sequences are permuted using the permutation sequences generated before,at last,the pixel's gray value's bit sequences are computed by using XOR operating and the binary sequences.

为了改进图像加密算法的安全性和效率，提出了一种基于三维混沌系统和位运算的数字图像加密算法，利用三维混沌序列的坐标分量分别产生置换序列和二值序列，在对待加密图像进行预处理的基础上，先应用混沌置换序列对预处理的结果图像进行基于灰度值位序列的置换操作，然后再应用产生的二值序列对结果图像的灰度值位序列进行位异或加密运算。

"I believe that the church in America, at this point in her history, is faced with the challenge of recapturing the Catholic vision of reality and presenting it, in an engaging and imaginative way, to a society which markets any number of recipes for human fulfillment," he said.
