Segmentation of brain MR images using an adaptively regularized kernel FCM algorithm with spatial constraints 基于空间约束的自适应正则化核FCM脑磁共振图像分割
Ran Fang, Yinan Lu, Xiaoni Liu, Zhuo Liu
FCM algorithm is a popular algorithm for medical image segmentation. The precise process of segmenting brain tissue images becomes more challenging in the presence of noise and other image artifacts. An improved adaptively regularized kernel FCM method is proposed in this paper. The spatial constraint function of membership is introduced to enhance clustering by adjusting the degree of influence between pixels and clustering centers. Experimental results on the brain images with different types and levels of noises demonstrate that the improved algorithm increases the accuracy of segmentation compared with the other soft clustering algorithms.

SAR image de-noising using local properties analysis and discrete non-separable shearlet transform 基于局部属性分析和离散不可分剪切波变换的SAR图像去噪
Ye Yuan, Liangzhuo Xie, Yewen Zhu, Sheng Wang, Zhemin Zhuang
A new SAR image de-noising approach that uses the local properties analysis of SAR image and the discrete nonseparable shearlet transform (DNST) is proposed in this paper. According to the local properties analysis method, the SAR image is divided into homogeneous region, non-homogeneous region and target region. The homogeneous region uses the average filter to de-noising. The non-homogeneous region uses the DNST transform to de-noising and target region is reserved directly. The experimental results show that the proposed approach can efficiently reduce the speckle noises and improve the edge-preserving ability.

Exploring trust and information monitoring for information security management 探索信息安全管理中的信任与信息监控
S. Chang, Anne Yenching Liu, Yu-Teng Jang
We investigated the employee's trust, commitment and compliance in the practice of information monitoring — an important information security management (ISM) issue for healthcare organizations to prevent employee misuse behaviors and safeguard sensitive information (e.g. medical records). Many studies have explored similar issues of information monitoring practice, but unfortunately they mostly overlook the domain attributes of ISM in reality. We studied the theories of privacy, trust, commitment and compliance to formulate a model for explaining the phenomenon observed in real work environment with organizational information monitoring in practice. Our research accomplished an advanced exploration of information monitoring for enhancing organizational ISM practices (ISMP).

Farmers are prone to be scratched when they are picking Chinese peppers by hands because of the thorns. Therefore, the safe and effective picking tools are extremely significant for the workers. But there is no one Chinese pepper picking tool that is really suitable for farmers. In this paper, four Sichuan pepper picking tool schemes are designed based on the TRIZ theory and they are evaluated by the triangular fuzzy number complementary judgment matrix. The evaluation indexes are marked by four raters. Calculating utility value and then we select the best scheme. And this paper may provide an evaluation method for the other product Designs.

Conditional image generation using feature-matching GAN 使用特征匹配GAN的条件图像生成
Yuzhong Liu, Qiyang Zhao, Cheng Jiang
Generative Adversarial Net is a frontier method of generative models for images, audios and videos. In this paper, we focus on conditional image generation and introduce conditional Feature-Matching Generative Adversarial Net to generate images from category labels. By visualizing state-of-art discriminative conditional generative models, we find these networks do not gain clear semantic concepts. Thus we design the loss function in the light of metric learning to measure semantic distance. The proposed model is evaluated on several well-known datasets. It is shown to be of higher perceptual quality and better diversity then existing generative models.

Random separation learning for neural network ensembles 神经网络集成的随机分离学习
Yong Liu
In order to prevent the individual neural networks from becoming similar in the long learning period of negative correlation learning for designing neural network ensembles, two approaches were adopted in this paper. The first approach is to replace large neural networks with small neural networks in neural network ensembles. Samll neural networks would be more practical in the real applications when the capability is limited. The second approach is to introduce random separation learning in negative correlation learning for each small neural network. The idea of random separation learning is to let each individual neural network learn differently on the randomly separated subsets of the given training samples. It has been found that the small neural networks could easily become weak and different each other by negative correlation learning with random separation learning. After applying large number of small neural networks for neural network ensembles, two combination methods were used to generate the output of the neural network ensembles while their performance had been compared.
在设计神经网络集成时,为了避免在负相关学习的长学习周期中单个神经网络变得相似,本文采用了两种方法。第一种方法是用神经网络集成中的小神经网络代替大神经网络。在能力有限的情况下,小型神经网络在实际应用中更为实用。第二种方法是在每个小神经网络的负相关学习中引入随机分离学习。随机分离学习的思想是让每个单独的神经网络在给定训练样本的随机分离子集上进行不同的学习。研究发现,采用负相关学习和随机分离学习的方法容易使小型神经网络变弱并产生差异。将大量的小神经网络应用于神经网络集成后,采用两种组合方法生成神经网络集成的输出,并对其性能进行比较。

Kai Cui, Hua Cai, Yao Zhang, Huan Chen
Nowadays, face recognition research has been widely concerned, and facial face feature point positioning, that is, face alignment is an important part of the face recognition process, the accuracy of positioning and positioning speed directly affect the face recognition effect. The face alignment task in the real scene becomes a very difficult problem because of the presence of factors such as different pose, expression, illumination and partial occlusion in face images. Aiming at these problems, this paper presents a face alignment method based on SURF of Scale Invariant Feature Transform, which can quickly detect and characterize the key points of face image. In addition, We use a coarse to fine auto-encoder networks to implement complex non-linear mapping of face to face shape. Finally, By comparing the AFLW data set, It shows that the mean error rate of this method is 1.84%-2.74% lower than that of the traditional method, and It also has a good effect in the calculation speed.
如今,人脸识别研究已受到广泛关注,而人脸特征点定位,即人脸对齐是人脸识别过程中的重要组成部分,定位的准确性和定位速度直接影响人脸识别效果。由于人脸图像中存在不同的姿态、表情、光照和局部遮挡等因素,使得真实场景中的人脸对齐成为一个非常困难的问题。针对这些问题,本文提出了一种基于尺度不变特征变换SURF的人脸对齐方法,该方法可以快速检测和表征人脸图像的关键点。此外,我们使用粗到细的自编码器网络来实现复杂的非线性人脸到人脸形状的映射。最后,通过对AFLW数据集的比较,表明该方法的平均错误率比传统方法低1.84%-2.74%,并且在计算速度上也有很好的效果。

Guang Li, Maolin Li, Dan Liu, Guanghua Xu, Shi-Lin Zhou
The decision process of the traditional mechanical equipment fault diagnosis method is invisible; it is similar to the black box operation and difficult to find the hidden knowledge in the data. Aiming at this problem, a fault diagnosis method of mechanical equipment is proposed based on data visualization. Firstly the data is flattened based on the constellation, and taking into account the different contribution that each data plays, the weight of each feature data is optimized by genetic algorithm, and then the fault diagnosis model based on data visualization is constructed by using the boundary form of the plane point set. Finally the results of the experiments on gearbox test experiment reveal that the proposed method is superior to the K-Neighborhood method and accurate for the fault diagnosis.

Bihan Zhang, Chuchu Ding, Wei Yan, Li Guo, Jun Wang, F. Hou
In this paper, we symbolize two kinds of different channels of Magnetoencephalography(MEG) and analyze their coupling relationship using symbolic transfer entropy algorithm. We record MEG signals from six depressive disorders and nine healthy subjects stimulated by positive, neutral, and negative emotional pictures and explore coupling relationship of different MEG channels. The results show that there are obvious differences on correlations between two channels of MLP32 and MRP32 with positive emotional stimulus, MLP31 and MRP31 with neutral emotional stimulus, MLP53 and MRP53 with negative emotional stimulus. In general, these channels have more correlation in patients with major depression, and can be able to distinguish depression patient from crowd. It also shows that the research of symbolic transfer entropy in MEG channel can distinguish the difference between normal and case samples, which of significance for clinical pathological estimation and diagnosis.
本文采用符号传递熵算法对两种不同的脑磁图通道进行符号化,分析了它们之间的耦合关系。我们记录了6名抑郁症患者和9名健康受试者在积极、中性和消极情绪图片刺激下的脑电信号,探讨了脑电信号不同通道的耦合关系。结果表明,MLP32和MRP32通道与积极情绪刺激、MLP31和MRP31与中性情绪刺激、MLP53和MRP53与消极情绪刺激的相关性存在明显差异。总的来说,这些通道在重度抑郁症患者中相关性更强,可以区分抑郁症患者和人群。研究脑磁图通道的符号传递熵可以区分正常样本和病例样本,对临床病理判断和诊断具有重要意义。

Improvement and implementation of video image de-hazing algorithm based on FPGA 基于FPGA的视频图像去雾算法的改进与实现
Guangwen Liu, Hua Cai, Yang Yang, Z. Geng
Aiming at the problems of color distortion and halos existing in video images in the process of transplanting dark channel prior algorithm of de-hazing into FPGA and considering the algorithm implementation in FPGA and the real-time requirement of video processing, an improvement algorithm base on FPGA is proposed in this paper. By refining the dark channel to obtain the final transmittance for eliminating the halos and by effectively segmenting the bright regions like the sky regions, the color distortion can be eliminated through the non-linear compensation for the regional transmittance. Through the verification of MATLAB simulation and the experiment of FPGA hardware, the system can effectively solve above problems. The experimental results show that on the premise of ensuring the output video quality, the system can better de-haze and eliminate halos in video images.
