Healthcare is one of the core areas in medical domain. In healthcare the data exist in various forms like respiration data, blood pressure readings, prescriptions and others. The data may help in decision-making for different initiatives in order to provide better healthcare services. However, in order to make this possible there is a need to diagnose the data in a professional way. Currently, there is a lack of a system or way which may help in decision-making in big data analysis in the form of phases. In this research, a framework has been proposed to diagnose the healthcare data for efficient data analysis.
医疗保健是医学领域的核心领域之一。在医疗保健中,数据以各种形式存在,如呼吸数据、血压读数、处方等。这些数据可能有助于制定不同举措的决策,以提供更好的医疗保健服务。然而,为了使这成为可能,需要以专业的方式对数据进行诊断。目前,在以阶段形式进行的大数据分析中,缺乏一种能够帮助决策的系统或方法。在本研究中,提出了一个诊断医疗保健数据的框架,以进行有效的数据分析。

Earth observation (EO) satellite data includes geospatial information (GI), which is a significant source to help human being to understand the situation of the earth ecosystem. Due to the large volume and heterogeneity of the geospatial data, sharing and integrating the geospatial data are a huge issue for GI catalog services. The catalog service specification implemented by a working group co-lead by Key Laboratory of Quantitive Remote Sensing Information Technology (QRSIT) of Chinese Academy of Sciences utilizes the OpenSearch (OS) protocol to centralize and integrate heterogeneous satellite data from different satellite data centers and enables the heterogeneous geospatial metadata to retrieve. This paper mainly concentrates on the specification of OpenSearch Description Document (OSDD), the structure of the catalog service, and the approach to search EO satellite data.

These days satellite images are being used in different fields, so it is essential for those images to have high resolution. Satellite images are affected by various factors in space such as: absorption, scattering, etc. Resolution of those images is very low. To have better perception of these images it is necessary to have the image with clear and well defined edges, which provides better visible line of separation. Resolution enhancement of these images has always been a major issue to extract more information from them. GEO Satellite imagery is an important tool and can be used to estimate rainfall during the thunderstorms and hurricanes for flash flood warnings in real time. However, for the GEO satellite is located higher than normal LEO satellite, the spatial resolution images are lower. Therefore, in order to obtain an image with enough resolution, some methods are to be implemented in GEO satellite observation such as: resolution enhancement which is a technique that achieves higher resolution for satellite image with lower resolution. There are many approaches that can be used to enhance the resolution of a satellite image. This paper focuses on the comparison between two techniques that are used to increase resolution of the images. Noise and sampling interval techniques, the two algorithms are shown via simulation. The simulation is introduced, and the results are discussed.
如今,卫星图像被用于不同的领域,因此这些图像的高分辨率是必不可少的。卫星图像受空间中各种因素的影响,如:吸收、散射等。这些图像的分辨率很低。为了更好地感知这些图像,有必要使图像具有清晰和明确的边缘,这提供了更好的可见分隔线。提高这些图像的分辨率一直是提取更多信息的一个主要问题。地球同步轨道卫星图像是一个重要的工具,可以用来估计雷暴和飓风期间的降雨量,实时发布山洪预警。然而,由于GEO卫星的位置高于普通LEO卫星,因此图像的空间分辨率较低。因此,为了获得足够分辨率的图像,在GEO卫星观测中需要采用一些方法,如:分辨率增强技术,即在较低分辨率的卫星图像上实现更高分辨率的技术。有许多方法可以用来提高卫星图像的分辨率。本文着重对两种提高图像分辨率的技术进行了比较。采用噪声和采样间隔技术,对这两种算法进行了仿真。介绍了仿真过程,并对仿真结果进行了讨论。

A novel visual tracking with occlusion detection via sparse coefficient analysis 基于稀疏系数分析的遮挡检测视觉跟踪方法

In recently years, visual tracking has achieved great development in the field of computer vision. But occlusion remains a challenging problem. Though sparse representation has been introduced into visual tracking, most of existing visual tracking methods based sparse representation treat the occlusion challenges as one of the special scenes simply, and did not make full use of sparse coefficient. In this paper, a novel occlusion detection via sparse analysis is proposed. We can judge whether the occlusion is happening and determine the definite occlusion area in current frame. And the detection result is introduced into the process of visual tracking in order to exclude the influence of occluding area of target object. In addition, we put forward a novel template update strategy. Both of these strategies collectively help the tracker to reduce the probability of drifting. Experimental results on a series of challenging image sequences demonstrate that the proposed visual tracking method achieves more favorable performance than other state-of-the-art tracking methods.
近年来,视觉跟踪在计算机视觉领域取得了很大的发展。但闭塞仍然是一个具有挑战性的问题。虽然稀疏表示已被引入到视觉跟踪中,但现有的基于稀疏表示的视觉跟踪方法大多将遮挡挑战作为一种特殊场景进行简单处理,没有充分利用稀疏系数。本文提出了一种基于稀疏分析的遮挡检测方法。我们可以判断当前帧中是否发生遮挡,并确定遮挡的确切区域。并将检测结果引入到视觉跟踪过程中,以排除目标物体遮挡区域的影响。此外,我们还提出了一种新的模板更新策略。这两种策略共同帮助跟踪器减少漂移的可能性。在一系列具有挑战性的图像序列上的实验结果表明,所提出的视觉跟踪方法比其他先进的跟踪方法具有更好的性能。

Sign language is a kind of important communication gesture to be studied in the human-computer interaction filed. Kinect is a 3D somatosensory camera launched by Microsoft, which can capture the color, depth and skeleton frames and is helpful to the gesture recognition research. In this paper, a method using the HOG and SVM algorithms with the Kinect software libraries to recognize sign language by recognizing the hand position, hand shape and hand action features is proposed. In order to realize this method, a special 3D sign language dataset contains 72 words is collected with Kinect, and experiments are conducted to evaluate the method. It is shown in the experimental results that the use of the HOG and SVM algorithms significantly increases the recognition accuracy of the Kinect, and is insensitive to background and other factors. The average recognition rate is up to 89.8%, which means the Kinect-based recognition method proposed in this paper can effectively and efficiently recognize sign language, and it has a great significance to the research and promotion of the sign language recognition technology.
手语是人机交互领域研究的一种重要的交流手势。Kinect是微软公司推出的3D体感相机,可以捕捉颜色、深度和骨架帧,有助于手势识别的研究。本文提出了一种利用HOG和SVM算法结合Kinect软件库,通过识别手的位置、手的形状和手的动作特征来识别手语的方法。为了实现该方法,利用Kinect采集了一个包含72个单词的专用三维手语数据集,并对该方法进行了实验验证。实验结果表明,HOG和SVM算法的使用显著提高了Kinect的识别精度,并且对背景等因素不敏感。平均识别率高达89.8%,表明本文提出的基于kinect的识别方法能够有效、高效地识别手语,对手语识别技术的研究和推广具有重要意义。

Focused on the issue that the robustness of traditional Mel Frequency Cepstral Coefficients (MFCC) feature degrades drastically in speaker recognition system, a kind algorithm that based improved Gammatone Frequency Cepstral Coefficients (GFCC) is proposed. The different between traditional MFCC and GFCC is that GFCC uses Gammatone filter bank to replace Mel filter bank to improve robustness. On this basis, this paper proposes one way that use Multitaper Estimation, MVA (Mean Subtraction, Variance Normzlization and Autoregressive Moving Average Filter)and other technologies to further enhance its robustness and tested with TIMIT speech database. The experimental results show that under different noise and different SNR, the improved GFCC that proposed by this paper has the lowest equal error rate and the best robustness, especially in the noise ratio is lower than 10dB, has greater advantage compared to other algorithms.
针对传统的Mel频率倒谱系数(MFCC)特征在说话人识别系统中鲁棒性急剧下降的问题,提出了一种基于改进Gammatone频率倒谱系数(GFCC)的说话人识别算法。传统MFCC与GFCC的不同之处在于,GFCC使用Gammatone滤波器组代替Mel滤波器组来提高鲁棒性。在此基础上,本文提出了一种利用多渐估计、MVA (Mean Subtraction, Variance normizzation and Autoregressive Moving Average Filter)等技术进一步增强鲁棒性的方法,并在TIMIT语音数据库中进行了测试。实验结果表明,在不同噪声和不同信噪比下,本文提出的改进GFCC具有最低的等错误率和最佳的鲁棒性,特别是在噪声比低于10dB的情况下,与其他算法相比具有更大的优势。

Compared with traditional cryptography, biometric cryptosystems provide more convenient and safe protection of keys. In this paper, an effective scheme for biometric cryptosystems based on the intersections of hyper-plane and hashed discrete space is proposed. Only genuine feature vectors, which are located on the hyper-plane, find the correct solution. Several tricks are provided to ensure the security of proposed scheme. Experiments have shown that our method achieved approximate performance compared with one of the latest methods based on fuzzy vault. However, our method is less complex than fuzzy vault based methods.

Simultaneous wireless information and energy transfer (SWIET) is a promising energy harvesting (EH) technique to power energy-constrained wireless nodes in wireless communications. In wireless relay networks, employing SWIET at the source-to-relay link, an energy-constrained relay node can harvest energy from the radio-frequency (RF) signals transmitted by a source node while assisting information relaying, and thus its lifetime can be prolonged. This paper investigate the resource allocation in a SWIET-based two-hop amply-and-forward or decode-and-forward relay network with a power-splitting EH receiver at the relay. The goal is to maximize the end-to-end achievable rate. Firstly, this paper formulate the resource allocation problem as a non-convex optimization problem. Then, this paper transform the non-convex problem into a convex problem by algebraic transformations. By solving the convex problem, this paper obtain the optimal resource allocation policy for the AF or DF relay network. Simulation results verify the optimality of the proposed resource allocation policy in this paper.
同步无线信息和能量传输(SWIET)是一种很有前途的能量收集(EH)技术,用于为无线通信中能量受限的无线节点供电。在无线中继网络中,在源到中继链路上采用SWIET,能量受限的中继节点可以在辅助信息中继的同时从源节点传输的射频(RF)信号中获取能量,因此可以延长其寿命。本文研究了基于sweet的两跳放转发或译码转发中继网络中的资源分配问题。目标是最大化端到端可实现的速率。首先,本文将资源分配问题表述为非凸优化问题。然后,利用代数变换将非凸问题转化为凸问题。通过求解该凸问题,得到了AF或DF中继网络的最优资源分配策略。仿真结果验证了本文提出的资源分配策略的最优性。
