Because the existing object tracking algorithm, which is based on Scale-invariant feature Transform (SIFT) and Particle Filter (PF), will make the feature points of target model be all deleted and not be added during the period of the full occlusion of the target, it isn’t able to work. According to this problem, this paper introduced adaptive updating target model and object matching. The specific method is taking a object tracking method of SIFT and PF, taking Random sample consensus (RANSAC) to exclude error matching, stopping updating object model while establishing candidate one due to the losing of tracking object, and matching objects by Best Bin First (BBF) optimized by k-dimensional tree (k-d tree). The simulation results show that this method was robustness when the object reappeared after full occlusion.","PeriodicalId":166878,"journal":{"name":"2018 10th International Conference on Communications, Circuits and Systems (ICCCAS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130549931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome the trade-off between wide bandwidth and high ranging resolution in the conventional FMCW radars, a dual-BPF regenerative FM demodulator and a time-to-digital converter (TDC) are utilized to achieve low power, low complexity, and fine ranging resolution. In the transmitter, a slew rate controlled relaxation oscillator and a 3-stage RF voltage-controlled oscillator (VCO) are hired to perform frequency modulation with significant power savings. In addition, a successive approximation register (SAR) logic based automatic frequency calibration (AFC) loop is placed in the transmitter to calibrate the frequencies of the oscillators for process, voltage and temperature (PVT) robustness consideration. The proposed transceiver with 3.3mW power consumption and −110dBm sensitivity, features sub-cm ranging capability, better than the conventional designs with tens of centimeters resolution.","PeriodicalId":166878,"journal":{"name":"2018 10th International Conference on Communications, Circuits and Systems (ICCCAS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132069836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method is based on the twice scan method of the connected area, and implemented on FPGA, called two-row scan method. It needs to save only two rows of pixels and it is only one pixel in every scan unit. Because of scanning two rows of pixels every time, the real-time performance is extremely excellent. After calculating the area of the connected area, it will be selected and removed according to the upper limit and the lower limit while the location of the material is determined by the channel division algorithm and the high speed air valve.

In this paper, a new approach of heterogeneous wireless network for SDG based on the chi-square distance is proposed and investigated. The algorithm firstly estimate weights of network attributes using analytic hierarchy process(AHP) according to different types of service which depends more on the consideration for the user side. Secondly, the CRITIC and anti-entropy weighting method are used to determine the objective weight according to the actual network parameters, and the final weight is obtained by the comprehensive weighting method based on the alignment minimization. Finally measure the chi-square distance from each candidate network to the ideal network, and the candidate network of smallest chi-square distance is the best access network.","PeriodicalId":166878,"journal":{"name":"2018 10th International Conference on Communications, Circuits and Systems (ICCCAS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123606519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, security of IoT is more concern because every device is connected through internet network, and eavesdroppers are ready to steal or even uncover our private data. Therefore, in this paper, we propose joint single relay and jammer selection (JSRJS) to enhance the physical layer security (PLS) of IoT. Moreover, outage probability (OP) and intercept probability (IP) as well as the system tradeoff performance (STP) for JSRJS under Nakagami-m fading channel are analyzed, and OP、IP as well as STP of JSRJS are all compared with that of the pure single relay selection (SRS), respectively. Simulation results show that the OP of JSRJS is the same as that of SRS, while the IP of JSRJS is always better than that of SRS. In addition, the STP for JSRJS is also more perfect than that of SRS. Besides, as the number of relay nodes increases, the STP of these two approaches both improve notably.","PeriodicalId":166878,"journal":{"name":"2018 10th International Conference on Communications, Circuits and Systems (ICCCAS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128168526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The channel number of the TI-ADC and the corresponding digital calibration could adapt to the input frequency, which would significantly decrease the power consumption of the TI-ADC as well as reduce the complexity of the digital calibration. In the proposed structure, the input signal is firstly fed into the power detector to roughly determine the range of the input frequency. Then the TI-ADC system activates the required sub-ADC channels accordingly and the calibration module changes to adapt to the input signal.
