Retina-imitation sampling based binary descriptor by Qingsheng YUAN, Guoqing JIN, Dongming ZHANG, Xiuguo BAO

“…The existing binary descriptors，generated from random or uniform point pairs sampling，suffer from low robustness and high computation.A novel sampling method,named RBS (retina-imitation based sampling),was proposed， which combines different densities sampling,multi-scale smoothing and reception field overlapping to imitate the converting from light signal to vision of ganglion cells of human retina cells,and further selects most discriminative comparison pairs based on learning on training data.Finally，compact binary descriptor was generated based on comparisons between the neighbor mean instead of singe sampled point.The experimental results show the RBS-128 with 128 bit outperforms FREAK and BRSIK with 512 bit about 16.4% and 5.3% in precision on the dataset provided by Mikolajczyk.…”

Detection of Intermittent Fault for Discrete-Time Systems with Output Dead-Zone: A Variant Tobit Kalman Filtering Approach by Jie Huang, Xiao He

“…Dead-zone phenomenon exists in many real practical systems due to the employment of low-cost commercial off-the-shelf sensors. Two Bernoulli random variables are utilized to model the dead-zone effect and a variant formation of Tobit Kalman filter is brought forward to generate a residual that can indicate the occurrence of an intermittent fault. …”

Monogamy relations for relativistically causal correlations by Mirjam Weilenmann

“…Here we show that correlations satisfying only this subset of constraints have to satisfy highly non-local monogamy relations between the effects of space-like separated random variables. These monogamy relations take the form of entropic inequalities between the various systems and we give a general method to derive them. …”

A Rateless Code Transmission Strategy Based on Real Time Service by Shaohua Zhao, Wei Chen, Bo Bai, Zhisheng Niu, Zhigang Cao

“…Rateless codes has the advantage of good channel adaptivity with a low amount of feedback data.However,the data transmission delay caused by its own coding characteristics and its sensitivity of the feedback link quality directly affects its application in real-time data transmission services.The random delay of feedback ACK which reduce the LT coding's performance was discussed,and then a new LT code based real-time transmission strategy was proposed to address the impact of non-ideal conditions of the feedback link.This strategy can achieve higher data throughout in non-ideal feedback conditions.…”

Provably secure certificateless aggregate signature scheme in wireless roaming authentication by Zhi-yan XU, Li-bing WU, Li LI, De-biao HE

“…Certificateless aggregate signature (CLAS) schemes have been widely applied in resource-constrained wireless mobile networks,because they could not only realize batch validation but also solve the certificate management and key escrow problems.It was shown that a certificateless aggregate signature in an anonymous roaming authentication scheme was vulnerable to the signature forge attack.To address the issue,a new secure and efficient certificateless aggregate signature scheme was presented,which required no bilinear pairing operations.And then the security of the scheme under the ECDLP assumption in the random oracle model was proved.Finally the performance of proposed scheme was evaluated.Compared with the original scheme,the proposal is more secure and the total computational cost is greatly reduced .…”
