salient regions detection is a very popular topic in pattern recognition. A novel method was presented to detect salient regions using color volume and edge in the manner of simulating visual attention mechanism. In order to detect salient regions, we have combined color volume and edge cues together and used them as the primary visual features. Color and edge are important cues that attract human's attention. It can enhance the broad outline of the saliency regions. The results of the experiment validate that the proposed method can efficiently detect salient regions and outperform some famous methods in term of precision/recall and F-measure metrics on MSRA1000 dataset and ECSSD dataset.

It is very important to develop precise statistical model for the high-resolution SAR images. The accurate distribution modeling of SAR images is the main contribution of this paper. In this paper, we study the GEV distribution model which can be used for modeling high-resolution SAR images, and introduce the properties and parameter estimation methods. In order to quantitatively assess the fitting result, we adopt the Kullback-Leibler divergence and the mean squared error as a similarity measurement. Experiment results with high-resolution SAR images indicate that the proposed GEV model can achieve satisfactory performance improvement in describing the statistical distribution of SAR image, not only in the homogeneous area, but also in the heterogeneous area.

A multi-channel calibration system is designed to calibrate the pressure sensor in this paper. It composes of digital multimeter (DMM), high performance pressure generator, digital pressure calibrator and computer. Almost 10 pressure sensors can be calibrated at the same time. The upper software of this system is programmed by LabVIEW2014, which has four functions: data acquisition, information processing, error calculation and report generation. A sensor is calibrated by this system to validate the accuracy of this system. The experimental result shows that the pressure measuring range of the designed calibration system is 0 to 60MPa, the pressure accuracy class and the pressure fluctuation rate are superior to 0.05%F·S and 0.01%F·S respectively. It indicates that this multi-channel calibration system can meet the accuracy requirements of pressure sensor calibration.

The earliest launch time of ship-to-air missile (SAM) is an important indicator to intercept the target. The calculation model under formation condition is more complex than that of a single ship. This paper analyzed the constraint conditions that affected the kill and launch zone of SAM on the base of anti-missile process of warship formation, built calculation models on the earliest launch time of SAM, and the results were analyzed. The results show that position configuration of ships and target orientations have obvious impact on the earliest launch time of SAM. The commander should draw up a highly active and rational plan based on the different battlefield situations to develop the maximal potential of SAM.

In order to improve the docking success rate in Automated Aerial Refueling (AAR), it is important to identify the receiver aircraft's receptacle for boom receptacle refueling (BRR). Meanshift tracking algorithm only considers the H component color statistics of the target area, lacking spatial information, could easily lead to inaccurate tracking. Besides, Meanshift tracking algorithm could easily lost target under occlusion conditions. To handle these situations, this paper proposes an improved Meanshift tracking algorithm based on color fusion and kernel function combined with Kalman filter (IMS_KF). In view of lacking color component, use RGB linear fusion. In view of lacking spatial information, define the kernel function by setting different weight to pixels, on the basis of the distance from the center point of target to the current point. In view of occlusion conditions, use Kalman Filter algorithm to estimate the location of moving targets. Meanshift tracking results will determine whether use Kalman forecasting. We implemented this algorithm on F-16 simulation experiment platform and the results reveal that our method meets industrial real-time requirements and has a better tracking robustness under a complex environment.

The parallel manipulator has some advantages of high accuracy, high speed and high stiffness etc. It makes up for the shortcomings of serial robot. So the parallel mechanism becomes a potential motion platform with high speed and high accuracy. Six poles parallel robot improves these defects of more singularity, poor load capacity and low stiffness which exist in workspace of the classic plane five poles parallel mechanism. Inverse and forward kinematic models are established based on the structure of the robot. The influence of foundation beds' location error, driving angle error and rod processing error on control accuracy is systematically analyzed. The theoretical foundation has been provided for realizing the optimal design of the robot and control in high accuracy.

In this paper, a realtime testbed for Software Defined Networks (SDN) was implemented using Raspberry Pi as OpenFlow (OF) switches. The implemented testbed provides practical development and testing environment for SDNs. Open vSwitch (OVS) was used to observe the flows and events in the network. With the POX integration, this paper easily provide detailed analysis results for any testing process. Additionally, this study implemented priority queuing algorithm, which manages the flows with respect to their QoS requirements. Priority queuing is a scheduling mechanism that provides a fixed number of priority levels to different service classes and can be used for differentiated services provisioning. Differentiated service is a QoS architecture that seeks to provide service differentiation to a small number of service classes. Finally, this study physically implemented the proposed algorithm to our testbed and validate the improvements of traffic and network utilization in terms of throughput.
