论严文井童话的诗意

严文井是继叶圣陶、张天翼之后最具有中国特色的童话作家之一。他的童话作品具有浓郁的诗意。诗意是严文井童话创作的有意追求。这种诗意来自优美纯净的语言、生动的艺术形象、真挚的情感以及灵动的幻想。这四个方面共同构建了他富有诗的意境,诗的美感,洋溢着动人诗情的童话世界。     

视译误读面面观

视译是口译领域里极少为研究者涉足、但误用误读现象较多的一个议题。为澄清相关概念,纠正术语使用不规范现象,首先应杜绝使用＂视译＂这一简称,代之以＂视阅口译＂与＂视听口译＂以供区分;其次,应将＂视阅口译＂与＂视听口译＂从同传和交传的范畴内区分出来,还其本来面目,以独立的身份与同传交传并列为口译形式之一;最后,需消除视阅口译仅作为同传训练踏脚石的印象,应将其视为一项复杂的口译活动进行专门化的系统培训。     

Computed tomography using level set method and algebraic reconstruction technique

In this paper, a novel reconstruction technique based on level set method and algebraic reconstruction technique is proposed for multiphase flow computed tomography (CT) system. The curvature-driven noise reduction method is inserted into the conventional iteration procedure of algebraic reconstruction technique to improve the image quality and convergence speed with limited projection data. By evolving the image as a set of iso-intensity contours after each updation, the sufficient number of iterations for acceptable results is reduced by 80%-90%, while the image quality is enhanced obviously. Quantitative evaluation of image quality is given by using both relative image error and correlation coefficient. The resultant images can be utilized to detect flow regimes for monitoring industrial multiphase flow. Laboratory results demonstrate the feasibility of the proposed method. Phantoms of four typical flow regimes can be reconstructed from few-view projection data efficiently, and the corresponding image errors and correlation coefficients are acceptable for the cases tested in this paper.     

Length-based vehicle classification in multi-lane traffic flow

For the realtime classification of moving vehicles in the multi-lane traffic video sequences, a length-based method is proposed. To extract the moving regions of interest, the difference image between the updated background and current frame is obtained by using background subtraction, and then an edge-based shadow removal algorithm is implemented. Moreover, a thresholding segmentation method for the region detection of moving vehicle based on location search is developed. At the estimation stage, a registration line is set up in the detection area, then the vehicle length is estimated with the horizontal projection technique as soon as the vehicle leaves the registration line. Lastly, the vehicle is classified according to its length and the classification threshold. The proposed method is different from traditional methods that require complex camera calibrations. It calculates the pixel-based vehicle length by using uncalibrated traffic video sequences at lower computational cost. Furthermore, only one registration line is set up, which has high flexibility. Experimental results of three traffic video sequences show that the classification accuracies for the large and small vehicles are 97.1% and 96.7% respectively, which demonstrates the effectiveness of the proposed method.     

彩色图像的数字水印系统设计

针对数字产品的版权保护问题,利用二维离散整数小波变换的快速性,结合人类视觉系统特性,开发了一种基于彩色图像新的、简单的、鲁棒性盲水印嵌入系统.系统可以将水印信息嵌入到不同整数小波分解级数下的彩色载体图像中去,具有嵌入速度快、安全性高的特点.首先将彩色载体图像由RGB彩色空间转换到YUV空间,再对y分量进行多级整数小波分解,然后分别将有意义的二值图像和字符串作为水印嵌入到不同级数小波分解后的低频域(LLn).算法选择了合适的水印嵌入位置,实验结果证明:系统使图像的不可见性好,所嵌入的水印对一般的图像处理攻击,如噪声、滤波、旋转、压缩等有较强的鲁棒性,系统实用性较强.

一种基于Harris角点特征精确匹配的图像拼接方法

提出了一种基于Harris角点特征的精确匹配方法。该方法首先提取参考图像及待拼接图像中各自的Harris角点点集,并计算出这2个点集间每对点的圆形邻域图像的相关系数;再通过提取各个角点邻域的Hu矩特征,获得了该特征下每对点的相似程度。将不同特征下的相似度进行归一化并融合,构造出2个点集间,每对点的相似度表。在此表的基础上,优化匹配结果,使得匹配点对的总体相似程度高,从而得到精确匹配。由于Hu矩特征具有旋转及尺度不变性,因此提取出的角点特征能够较好地抵抗常见的图像变换。最后,实现了一套包括图像预处理、图像对齐与匹配等诸多模块的图像拼接系统。通过实际操作表明,该方法的图像拼接效率较高,有较好的鲁棒性。     

“竹帘”背后的中国——1949-1971年《时代》周刊的中国报道评析

1949.10.1-1971.4.9《时代》周刊的报道中所呈现的中国,是一个极度负面的＂风雨飘摇的邪恶帝国＂的形象,这一形象与中国的实际情况相距较远,其报道存在比较明显的不准确和片面的成分。导致这一时期《时代》周刊对中国的报道不太客观公正的原因主要有二：一是其持有强烈的＂反共主义＂意识形态;二是其将中国视为严重威胁美国国家利益的敌人。     

关联理论及关联翻译理论在口译中的应用探析

口译是一种跨语言、跨文化的动态的双语交际活动.利用关联理论及关联翻译理论的强大解释力阐述口译的过程,分析译员在口译过程中讲话者和受话者的双重角色,并进一步针对译员如何成功塑造其双重角色及改善自身认知环境提出一些有效的建议,如必要的口译预期,谙习文化差异,积累图式知识等,从而使译员能够较充分地发挥其在口译活动中的主观能动作用,这对译员成功地完成口译交际活动将起到积极作用.
