The color cast images usually have serious loss of the color information and are inconvenient for visual observation and image analysis. To tackle this problem, a novel two-stage image color cast correction scheme is proposed in this paper. Firstly, the proposed approach performs the color cast and stable channel detection by using extreme intensity ratio of the original image. Second, the distorted image color is restored by solving the constrained problem with the degree of color variation and the above-detected color cast and stable channel. The experimental results using surveillance videos demonstrate that the proposed scheme is not only feasible but also effectively. In addition, the results satisfy human subjective perception as well. © Springer-Verlag Berlin Heidelberg 2014.

Localization is one of the key technologies of wireless sensor networks (WSNs). This paper proposes a mobile anchor-assisted localization method for three-dimensional (3D) networks. In this method, an anchor is equipped with global positioning system (GPS) device, and traverses the network along the Hilbert space-filling curve. The ordinary nodes estimate their positions using trigonometric method based on the characteristics of Hilbert curve. We compare the localization error, communication cost, and computational complexity of our proposed algorithm and other existing mobile anchor-assisted algorithms. The simulation results show that our method is better than other methods. © 2014 Springer-Verlag Berlin Heidelberg.

On account of the characteristics of online Chinese-Vietnamese topic detection, we propose a Chinese-Vietnamese bilingual topic model based on the Recurrent Chinese Restaurant Process and integrated with event elements. First, the event elements, including the characters, the place and the time, will be extracted from the new dynamic bilingual news texts. Then the word pairs are tagged and aligned from the bilingual news and comments. Both the event elements and the aligned words are integrated into RCRP algorithm to construct the proposed bilingual topic detection model. Finally, we use the model to determine if the new documents will be grouped into a new category or classified into the existing categories, as a result, to detect a topic. Through the contrast experiment, the proposed model achieves a good effect on topic detection. © Springer-Verlag Berlin Heidelberg 2014.

As a result of rapid development, the Internet has become an indispensable tool in people's daily life, and web logs have been growing rapidly as well. How to deal with massive logs timely and extract information people need from the logs has become a problem;handling web log by single computer can not meet people's needs any more. Combining cloud computing and Hadoop technology, this paper established a new processing system for the collection of logs and remote parallelization analysis, which not only solved the issues of traditional systems that data handing and collection could not proceed simultaneously, but reduced the performance bottleneck of computing power and storage capacity, thereby saving much time and improving efficiency significantly. © (2014) Trans Tech Publications, Switzerland.

Ancient language manuscripts constitute a key part of the cultural heritage of mankind. As one of the most important languages, Chinese historical calligraphy work has contributed to not only the Chinese cultural heritage but also the world civilization at large, especially for Asia. To support deeper and more convenient appreciation of Chinese calligraphy works, based on our previous work on the probabilistic retrieval of historical Chinese calligraphic character manuscripts repositories, we propose a system framework of the multi-feature-based Chinese calligraphic character images probabilistic retrieval in the mobile cloud network environment, which is called the DPRC. To ensure retrieval efficiency, we further propose four enabling techniques: (1) DRL-based probability propagation, (2) optimal data placement scheme, (3) adaptive data robust transmission algorithm, and (4) index support filtering scheme. Comprehensive experiments are conducted to testify the effectiveness and efficiency of our proposed DPRC method. © 2014 ACM.

During the strip laminar cooling process, the switching of cooling valves is decided by different operating modes, initial and rolling-terminating conditions. Aimed at shortening the development cycle and at the same time assuring the quality and regularity of the controlling program, this paper has designed a hot strip laminar cooling prediction software adopting the RTW code generating technique. First, the Simulink model of the cooling process is built. Second, the model is converted by RTW into C code which can launch without Matlab. Finally, the graphical user interface design is completed with the generated code incorporated in. Experiment shows that the software developed with this method can gain the same results as Simulink model. The work of manual coding is substantially reduced. The combination of convenient modeling of Simulink and flexible GUI designing of VC can provide better reliability and practicability than traditional software developing. © (2014) Trans Tech Publications, Switzerland.

Tracking-by-detection has become an attractive tracking technique, which treats tracking as a category detection problem. However, the task in tracking is to search for a specific object, rather than an object category as in detection. In this paper, we propose a novel tracking framework based on exemplar detector rather than category detector. The proposed tracker is an ensemble of exemplar-based linear discriminant analysis (ELDA) detectors. Each detector is quite specific and discriminative, because it is trained by a single object instance and massive negatives. To improve its adaptivity, we update both object and background models. Experimental results on several challenging video sequences demonstrate the effectiveness and robustness of our tracking algorithm. © 2014 IEEE.

Object tracking in complex backgrounds with dramatic appearance variations is a challenging problem in computer vision. We tackle this problem by a novel approach that incorporates a deep learning architecture with an on-line AdaBoost framework. Inspired by its multi-level feature learning ability, a stacked denoising autoencoder (SDAE) is used to learn multi-level feature descriptors from a set of auxiliary images. Each layer of the SDAE, representing a different feature space, is subsequently transformed to a discriminative object/background deep neural network (DNN) classifier by adding a classification layer. By an on-line AdaBoost feature selection framework, the ensemble of the DNN classifiers is then updated on-line to robustly distinguish the target from the background. Experiments on an open tracking benchmark show promising results of the proposed tracker as compared with several state-of-the-art approaches.

In the cloud computing, there are massive functions and resources are encapsulated into Web services. The traditional web service registry systems normally using the central architecture can’t meet the requirements of cloud computing. A web service registry system based on structured P2P system with secure access and control is implemented. Multiple Universal Description, Discovery and Integration (UDDI) nodes are organized by the P2P based schedule and communication mechanism. The registration and discovery of Web services is redesigned to the new system that provides services like one single UDDI server. The experiment results show that the capacity can be extended dynamically and support large scalable access. © IFIP International Federation for information processing 2014.

In this paper, we present a saliency guided image object segment method. We suppose that saliency maps can indicate informative regions, and filter out background in images. To produce perceptual satisfactory salient objects, we use our bio-inspired saliency measure which integrating three factors: dissimilarity, spatial distance and central bias to compute saliency map. Then the saliency map is used as the importance map in the salient object segment method. Experimental results demonstrate that our method outperforms previous saliency detection method, yielding higher precision (0.7669) and better recall rates (0.825), F-Measure (0.7545), when evaluated using one of the largest publicly available data sets. © Springer International Publishing Switzerland 2014.
