利用双目立体视觉技术实现危险化学品仓库的三维重建是库内安全监测的有效手段,立体匹配是其中的重点和难点。提出一种利用加权sad算法和灰度共生矩阵的双目立体像对稠密匹配算法,该算法对传统sad匹配算法做出改进,引进服从二维高斯分布的加权系数求出初始视差图,然后结合灰度共生矩阵的4个纹理特征,利用图像纹理信息对空洞进行填充,得到了优化的视差结果。实验结果表明,该算法在标准数据集及仓库模型具有较好的适用性。

在立体匹配算法中,局部立体匹配中最常使用的算法为sad算法和census算法,文章通过分析两种算法的优点与缺点,并针对传统立体匹配精度较低这一问题,提出了一种基于多权值sad-Census立体匹配算法。首先,先计算出传统sad与传统census算法的匹配代价,再进行融合,在不同的自适应窗口中通过提供不同的权重从而进行聚合代价的计算。再通过利用赢家通吃算法以及一致性检测算法来进行视差优化和空洞填充,从而得到最终的视差图。实验结果表明,文章改进后的算法与传统sad算法和传统census算法相比,缩短了运行时间,提高了匹配的精度,增强实验结果的鲁棒性。

A Comparison Analysis Between Rooms and Home is So sad

第二十届全国心理学学术会议--心理学与国民心理健康

作者： Li Zhou Department of Psychology Jiangxi Normal University

Visual working memory(WM) for face identities is impaired when faces bear sad versus happy emotion. To clarify the stage at which expression play a role in memory for facial information, we isolated emotion(sad/happy) to the encoding phase(Experiment 1;neutral probe faces) or retrieval phase(Experiment 2;neutral study faces). WM was simply improved by sadness when emotion was present at encoding, indicating that retrieval stage was not affected by facial expression. To determine whether facial expression is maintained in WM, in Experiment 3 we inserted an emotional categorization task into the maintenance interval. Emotional congruence between word and face supported memory neither for sad nor for happy faces, suggesting that negative facial information is not maintained during WM maintenance. Our findings indicated that negative expressions only have a beneficial effect on WM at encoding.

作者：刘惠函 Hwa Chong Institution

There are similarities and differences in the construction of the two poems:Charlotte Mew’s"Rooms"and Philip Larkin’s"Home is so sad(HISS)".Both convey a sense of regret and loss through the portrayal of abandoned ***,"Rooms"highlights the despair upon the withering away of life and the slow,painful approach of death,while"HISS"expresses the pain upon the loss of loved *** rooms in each poem may have different roles in the lives of their owners,but in each case,they form a significant linkage of the past and present,and ultimately symbolise the abandonment of human heart itself.

Crystal Structure Theory and Applications 2013年第3期2卷 93-99页

作者： Sibi Narayanan Devadasan Velmurugan Centre of Advanced Study in Crystallography and Biophysics University of Madras Maraimalai (Guindy) Campus Chennai India

Current structural genomics projects aim to solve a large number of selected protein structures as fast as possible. High degree of automation and standardization is required at every step of the whole process to speed up protein structure determination. Phase problem is a bottleneck in macromolecular structure determination and also in model building which is a time-consuming task. The simplest approach to phasing macromolecular crystal structures is the use of a sad signal. sad data can be collected using the in-house copper (1.54 A) wavelength source. Data collected using copper wavelength with the incorporation of anomalously scattering heavy metal atoms may serve as a powerful tool for structural biologists to solve novel protein structures as well where synchrotron beam line is not available. A short soak of protein crystals in heavy metal solution or by incorporating heavy atoms into the protein drop while crystallizing the protein (co-crystallization) leads to incorporation of these heavy metal ions into the ordered solvent shell around the protein surface. The present work aims to determine whether cerium ion can be successfully incorporated into the protein crystal through quick-soaking method while maintaining the isomorphism. The study also aims in understanding whether this metal ion can be used for phasing purpose. The intensity data are collected and analyzed for anomalous signal, substructure solution and the binding sites.

In the 13th century, Marco Polo traveled a long way to China. He was a famous Italian 1 . During his stay in China, he saw many wonderful things. One of the things he 2 was that the Chinese used paper money. People in 3 countries didn’t use paper money until the 17th century. However, people in China began to use paper money in the 10th century. 4 was invented by a Chinese about 2,000 years ago. His name was Cai Lun. He then 5 these pieces of paper together and made them into a 6 . Now paper mainly comes from trees. We use it every day. Sometimes we waste a lot of it. If we keep on doing so, people have to cut down many more trees. Then there will not be any trees left. If there are no 7 , there will be no paper.
