The warning system of vehicles' driving safety based on network 基于网络的车辆行驶安全预警系统
Qingling Lu, Zhihui Wang, Wei Zhang, Yanbin Zhao
With the increase of vehicles ownership in the society, traffic security problem stands out. This paper proposes a warning strategy of vehicles' driving safety based on the vehicles networking. Receive the motion information sent from the adjacent vehicles through network and determine the position of the adjacent vehicles relative to the local vehicle when they have a higher speed. The people can use the danger value to evaluate the possibility of vehicle collision. If danger value exceeds the threshold, the warning comes into being. This strategy makes the vehicles acquire adjacent vehicles' information through the network. It has advantages of a wider range and stronger predictability. The warning system for safe driving of vehicles is composed of vehicle-mounted intelligent nodes and servers. The vehicle-mounted intelligent nodes obtain the motion information of vehicles through the OBD, GPS/inertial navigation and other sensors, and because of its connecting motors under steering wheel or seats, it will remind the driver by shaking when the warning produces, at the same time, dangerous vehicles and their motion information will be displayed on the navigation map.
随着社会车辆保有量的增加,交通安全问题日益突出。提出了一种基于车辆联网的车辆行驶安全预警策略。通过网络接收相邻车辆发送的运动信息,确定相邻车辆在速度较高时相对于本地车辆的位置。人们可以利用危险值来评估车辆发生碰撞的可能性。如果危险值超过阈值,就会产生警告。该策略使车辆通过网络获取相邻车辆的信息。它具有范围广、可预见性强的优点。车辆安全驾驶预警系统由车载智能节点和服务器组成。车载智能节点通过OBD、GPS/惯性导航等传感器获取车辆的运动信息,由于其连接在方向盘或座椅下的电机,在产生预警时通过晃动提醒驾驶员,同时将危险车辆及其运动信息显示在导航地图上。

Nearest neighbor-based instance selection for classification 基于最近邻的实例选择用于分类
G. Yu, Jin Tian, Minqiang Li
With the increasing size of big data, classifiers usually suffer from intractable computing and storage issues. Moreover, decision boundaries in complex classification problems are usually complicated and circuitous. Modeling on too many instances can sometimes cause oversensitivity to noise and degrade the learning accuracies. Instance selection offers an effective way to improve classification performance based on partial but significant data. This paper presents a novel instance selection algorithm based on nearest enemy information. The dataset is divided into several partitions corresponding to instances' nearest enemies. In every partition, representative instances are selected based on the distribution information to represent both sides of decision boundary. A support vector machine (SVM) is then adopted to conduct the classification model based on these representative instances. Experimental results illustrate that the proposed algorithm outperforms some conventional instance selection methods with higher classification accuracy and smaller size of selected instances.
随着大数据规模的不断扩大,分类器通常面临难以解决的计算和存储问题。此外,复杂分类问题中的决策边界通常是复杂和迂回的。在太多的实例上建模有时会导致对噪声过度敏感,从而降低学习的准确性。基于部分但重要的数据,实例选择是提高分类性能的有效方法。提出了一种新的基于最近敌人信息的实例选择算法。数据集被分成几个分区,对应于实例最近的敌人。在每个分区中,根据分布信息选择有代表性的实例来表示决策边界的两侧。然后采用支持向量机(SVM)对这些代表性实例进行分类建模。实验结果表明,该算法具有较高的分类精度和较小的选择实例规模,优于传统的实例选择方法。

An image mosaic method based on improving seam line 一种基于改进缝线的图像拼接方法
Qingpeng Liu, Hua Cai, Guangqiu Chen, Shuang Dou, Yong Yang
In the traditional image mosaic algorithm based on seam line, the line is searched by making the color and neighborhood structure difference as small as possible in the overlap region of the images. However, when a small object with single color and symmetrical structure appears, the color and the neighborhood structure difference are not able to restrain the direction of the seam line. The appearance of the seam line crossing the object leads to the deformity of the crossed object in the mosaic image. Aiming at this problem, the image contour energy based on the above two parts is proposed to punish seam line in this paper, which can change the direction of seam line. Experimental results show that the new energy formula used in this paper can effectively avoid the crossing and the deformity.
传统的基于拼接线的图像拼接算法是通过使图像重叠区域的颜色和邻域结构差异尽可能小来搜索拼接线。但是,当出现颜色单一且结构对称的小物体时,颜色和邻域结构差异无法约束缝线的方向。接缝线与物体交叉的出现,会导致拼接图像中交叉物体的变形。针对这一问题,本文提出了基于上述两部分的图像轮廓能量来惩罚缝线,可以改变缝线的方向。实验结果表明,本文所采用的新能量公式能有效地避免交叉和变形。

An effective blind image watermarking based on inter-blocks estimation and quantization index modulation 基于块间估计和量化指标调制的有效图像盲水印
Ling-Yuan Hsu, Hwai-Tsu Hu, Hsien-Hsin Chou
Watermarks are used to protect the copyright of multimedia and help us to identify legitimate ownership. Imperceptibility and robustness are always prime concern for the watermarking researchers. Therefore, a simple but effective blind watermarking scheme would be what we expect. In this study, we present a kind of blind watermarking technique, which is based on inter-blocks estimation of the discrete cosine transform (DCT) coefficients. To satisfy both imperceptibility and robustness requirements while maintaining a sufficient payload capacity, a quantization index modulation technique (QIM) DCT-based scheme is employed. This technique substantial reduces the effect of host data interference, thus having significant advantage over previously proposed DCT-based watermarking schemes. Experimental results show that the proposed scheme to embedding watermarks can effectively to defense various image attacks, especially in image compression attacks and Gaussian noise.
水印用于保护多媒体的版权,并帮助我们识别合法所有权。不可感知性和鲁棒性一直是水印研究人员关心的问题。因此,一种简单而有效的盲水印方案是我们所期望的。在本研究中,我们提出了一种基于离散余弦变换(DCT)系数块间估计的盲水印技术。为了在保持足够的有效载荷能力的同时满足不可感知性和鲁棒性要求,采用了一种基于量化指标调制技术(QIM)的dct方案。该技术大大减少了主机数据干扰的影响,因此与先前提出的基于dct的水印方案相比具有显著的优势。实验结果表明,该方法能够有效防御各种图像攻击,特别是图像压缩攻击和高斯噪声攻击。

Construction of Khmer entity annotation corpus based on constrained conditional random fields 基于约束条件随机场的高棉语实体标注语料库构建
Shuhui Huang, Xin Yan, Zhengtao Yu, Qingling Lei
It is hard to solve the problem of considerable segmentation error caused by out-of-vocabulary words, so for segmentation task based on Constrained Conditional Random Fields Model, the Precision is relatively low. To solve this problem, Constrained Conditional Random Fields Model, which exploits constraints on the Khmer word segmentation and named entity recognition, is proposed in this paper. With a series of segmentation, POS tagging and NER tasks, the Khmer entity annotation corpus which contains more entities is constructed. Several groups of experiments are set up in each link of construction entity annotation corpus. These experimental data have proven that the proposed method is feasible.
由于词汇外词导致的切分误差较大,难以解决,因此基于约束条件随机场模型的切分任务精度较低。针对这一问题,本文提出了约束条件随机场模型,该模型利用了高棉语分词和命名实体识别中的约束条件。通过一系列的分词、词性标注和NER任务,构建了包含更多实体的高棉语实体标注语料库。在构造实体标注语料库的每个环节都设置了几组实验。实验数据证明了该方法的可行性。

To solve this problem, Constrained Conditional Random Fields Model, which exploits constraints on the Khmer word segmentation and named entity recognition, is proposed in this paper. With a series of segmentation, POS tagging and NER tasks, the Khmer entity annotation corpus which contains more entities is constructed.
