The general edge extraction algorithm is not ideal to process infrared images, which is low contrast and blurred edge. In this paper, we used the multi-fractal spectrum to edge of infrared image. We extracted the edge information of the image and calculate the measure and fractal spectrum with multiple singular values of each pixel. Analysis of the similarities and differences of multiple measure, the function in edge extraction, meanwhile, analyzed the fiction of fractal characteristics to edge image extraction. This method differs from the traditional gradient algorithm，It determines whether the edge or not just according to the local extreme points, but according to the pixels in the local and global relationships to determine whether the pixel is a real edge. It can neglect important edge pixel and texture pixel，which is more in line with the human visual mental. It provide a good reference for recognition of infrared image and further processing. © 2016 SERSC.

In this paper, the complex modified projective synchronization(CMPS) of two different fractional-order chaotic complex systems is firstly investigated. We assume that the slave system is perturbed by external disturbances. The master and slave systems achieved CMPS can be synchronized up to a complex scaling matrix. On the basis of a novel stability theory, a robust control law is designed to realize the CMPS for two different fractional-order chaotic complex systems. The CMPS can be regarded as the generalization of several types of synchronization reported in existing literatures. Simulation results are given to verify the effectiveness and feasibility of the proposed synchronization scheme.

This paper presents a new algorithm to construct convex lifting for a given polyhedral partition whenever it exists. This algorithm exclusively relies on the halfspace representation of the regions in the respective partition. Also, this algorithm is applicable for the general polyhedral partitions of polyhedra, and thus overcomes the limitation on the polytopic partitions of the existing algorithm based on the vertex representation. Finally, the importance of the proposed algorithm is clarified via some numerical examples, in particular in implementation of piecewise affine controllers. Accordingly, the convex lifting concept is shown to be useful to both avoid storing the state-space partition and to facilitate the online evaluation.

Network embedding aims at projecting the network data into a low-dimensional feature space, where the nodes are represented as a unique feature vector and network structure can be effectively preserved. In recent years, more and more online application service sites can be represented as massive and complex networks, which are extremely challenging for traditional machine learning algorithms to deal with. Effective embedding of the complex network data into low-dimension feature representation can both save data storage space and enable traditional machine learning algorithms applicable to handle the network data. Network embedding performance will degrade greatly if the networks are of a sparse structure, like the emerging networks with few connections. In this paper, we propose to learn the embedding representation for a target emerging network based on the broad learning setting, where the emerging network is aligned with other external mature networks at the same time. To solve the problem, a new embedding framework, namely "Deep alIgned autoencoder based eMbEdding" (DIME), is introduced in this paper. DIME handles the diverse link and attribute in a unified analytic based on broad learning, and introduces the multiple aligned attributed heterogeneous social network concept to model the network structure. A set of meta paths are introduced in the paper, which define various kinds of connections among users via the heterogeneous link and attribute information. The closeness among users in the networks are defined as the meta proximity scores, which will be fed into DIME to learn the embedding vectors of users in the emerging network. Extensive experiments have been done on real-world aligned social networks, which have demonstrated the effectiveness of DIME in learning the emerging network embedding vectors.

As a special type of object detection, pedestrian detection in generic scenes has made a significant progress trained with large amounts of labeled training data manually. While the models trained with generic dataset work bad when they are directly used in specific scenes. With special viewpoints, flow light and backgrounds, datasets from specific scenes are much different from the datasets from generic scenes. In order to make the generic scene pedestrian detectors work well in specific scenes, the labeled data from specific scenes are needed to adapt the models to the specific scenes. While labeling the data manually spends much time and money, especially for specific scenes, each time with a new specific scene, large amounts of images must be labeled. What’s more, the labeling information is not so accurate in the pixels manually and different people make different labeling information. In this paper, we propose an ACP-based method, with augmented reality’s help, we build the virtual world of specific scenes, and make people walking in the virtual scenes where it is possible for them to appear to solve this problem of lacking labeled data and the results show that data from virtual world is helpful to adapt generic pedestrian detectors to specific scenes.

This paper is dedicated to a brief discussion on the nonlinear damping. We present the particular results for linear and nonlinear viscous dampers, for fractional damper and for the hysteretic damper. As a main purpose we consider the mathematical model of damper with hysteretic properties on the basis of the Ishlinsky-Prandtl model. The numerical results for the observable characteristics such as the force transmission function and the "force-displacement" transmission function are obtained and analyzed both for the cases of the periodic affection as well as for the impulse affection (in the form of δ-function). The comparison of the efficiency of nonlinear viscous damper and hysteretic damper is also presented and discussed. © Springer International Publishing AG 2018.

In cooperative relay networks with multiple users and multiple potential relays, which relay nodes are selected has great impact on the system performance. It is an optimization problem for selecting suitable relay nodes. The exhaustive search can solve this problem but the complexity will increase factorially with the network size, i.e., the number of users and the number of relays in the network. In this paper, we formulate both single-objective and multi-objective relay selection problems. For single-objective relay selection problem, only one system objective is considered. A novel quantum bee colony optimization (QBCO) based relay selection scheme is proposed. For multi-objective relay selection problem, two contradictive objectives are considered simultaneously. A novel non-dominated sorting quantum bee colony optimization (NSQBCO) based relay selection scheme is proposed. Simulation results show that the proposed relay selection schemes have the ability to find global optimal solution but have less computational complexity compared with exhaustive search scheme. © 2016 SERSC.
