Trajectory privacy protection mechanism of obfuscating paths based on vehicles cooperation by Ziwen ZHAO, Ayong YE, Junlin JIN, Lingyu MENG

“…Vehicles sent location information to third parties to obtain location-based services in the Internet of vehicles,which may lead to vehicle trajectory privacy leakage.To address the privacy problem,trajectory privacy protection mechanism of obfuscating paths based on vehicles cooperation was proposed.Firstly,after the vehicle trajectory entropy reaches the custom trajectory protection threshold,the overhead of paths confusion saves by reducing the number of vehicle paths confusion.Then,paths confusion algorithm was designed to increase chances of vehicle paths confusion at intersections,which can improve the degree of vehicle trajectory protection.Finally,the simulation experiment verified the validity and efficiency of the method from the trajectory entropy and trajectory tracking success rate.…”

Bandwidth extension method based on nonlinear audio characteristics classification by Li-yan ZHANG, Chang-chun BAO, Xin LIU, Xing-tao ZHANG

“…A bandwidth extension method based on audio classification was proposed.Time series of audio signals were classified into four types based on recurrence plot and recurrence quantification analysis,and the fine spectrums were recovered by taking advantage of four methods respectively.In addition,the spectrum envelope and energy gain were adjusted by Gaussian mixture model and codebook mapping on the basis of soft decision respectively.Subjective and objective testing results indicate that the proposed method has good quality compared with conventional blind bandwidth extension methods,and the performance of ITU-T G.722.1 codec with the proposed algorithm is better than that of G.722.1C codec at the same bit rate.…”

Pilot based channel estimation in amplify-and-forward MIMO relay networks by Jian ZHOU, Bao-yu ZHENG

“…A channel estimation method in two time slots for two-hop amplify-and-forward MIMO relay channels is pro-posed.An algorithm for computing the optimal pair of source pilot and relay amplify matrix is developed,which mini-mizes the mean square error of the source-to-relay channel estimation subject to both power constraints at the source and the relay.The signal matrices are decomposed into unitary components and diagonal components.Then the bisection method is used to obtain the optimal diagonal components of the source pilot and the relay amplified matrix.The simula-tion results show that the proposed method has no ambiguity in the channel estimates.The effects of the channel correla-tion and the number of antennas on the performance of channel estimation are also analyed.…”

Coupled bidirectional flow for adaptive image interpolation by FU Shu-jun 1, RUAN Qiu-qi 2, MU Cheng-po 3, WANG Wen-qia 1

“…An adaptive coupled bidirectional flow process was presenfed,where an inverse diffusion was performed to enhance edges along the normal directions to the isophote lines（edges）,while a normal diffusion was done to remove ar-tifacts（“jaggies”） along the tangent directions.The two converse diffusion forces were splitted into a coupled form to stop the cancellation between each other.In order to preserve image features,the nonlinear diffusion coefficients were locally adjusted according to the directional derivatives of the image.And then the above process was applied to image interpolation.Experimental results demonstrate that our interpolation algorithm substantially improves the subjective quality of the interpolated images over conventional interpolations and relative equations.…”
