This paper proposes a new method to detect objects in images. Boundaries contain shape of the objects. To detect objects in cluttered images, we use boundary fragments. Boundary fragments are obtained by our new training procedure. Poisson equation is used to divide edges and extract generic model of the object. Gaussian Mixture Model (GMM) is used to model shape of the object. This creates relation between local boundary fragments. To localize our desired object in image, a voting process is performed in Hough space. A scale adaptive search algorithm is used in this voting space to find the most probable regions of object presence. By learned GMM, shape of the object is obtained from test image. We remove false positives, usual problems in object detection tasks, by matching generic model to the extracted shapes. Local orientations histograms of the objects model are used for matching. We evaluate our method and compare with state-of-the-art methods. Experimental results show the power of our proposed method in detection and its robustness in face to scale and translation variations. © 2010 IEEE.

Intelligent Environments most commonly take a physical form such as homes, offices, hotels, restaurants, shops, that are equipped with advanced networked computer based systems, which enable better or new lifestyles for people. However, Intelligent Environments can also take the form of virtual online spaces such as SecondLife, which can both mimic the real world and provide functionalities which could not be provided in reality, such as advanced simulations and movement. There is the growing trend for people to spend more time in such virtual environments and, to these ends, this work in progress paper reports on a new project, +Spaces which is developing a range of virtual world tools for e-government applications, and presents some of the concepts and technical challenges involved in creating these intelligent virtual spaces for e-government. © 2010 IEEE.

We present a new method to learn the model based on object parts extraction and grammar which can be applied to classification and recognition. Our approach is invariant to the scale and rotation of the objects. We use Structural Context feature to detect object parts. It is done comparing SC histograms of the model and image. We extract oriented triplets from centers of detected parts. We define grammar for these parts using normalize distances and angles between them. We propose and compare two alternative implementations using different classifiers: Hidden Markov Model with mixture of Gaussian outputs (MHMM) and Adaptive Neuro-Fuzzy Inference system (ANFIS) to learn this grammar and estimate parameters of the model for each object class. The proposed method is computationally efficient and it is invariant to scale and rotation. Experimental results demonstrate the privileged performance of the proposed approach against other methods. © 2010 IEEE.

As we know, service-aware computing is an important part of pervasive computing for Web-based mobile application with uncertainty. We modified the fusion method of evidence information after considering context's reliability, time-efficiency, and relativity, which has improved the classical fusion rule of D-S (Dempster-Shafer) Evidence Theory when being used in the pervasive computing paradigm. We call it EDS. After extending the process, we overcome the drawbacks of classical D-S Evidence Theory. All these suggested technologies have been successfully used in our service-aware computing projects. The efficiency of our researches has been shown by our many application practices. © 2010 IEEE.

This paper presents an interactive robotics modeling and simulation system based on the MSRS (Microsoft Robotics Studio), called iRMSS (Interactive Robotics Modeling & Simulation System). iRMSS is composed of two sub systems. One is the 3D robotics modeling sub-system that facilitates the creation of segment-joint model and physical model for robots. The other is the interactive robotics simulation sub-system that can provide dynamics parameters feedback. So that iRMSS has the advantage of rapid robotics modeling and flexible parameter feedback over the MSRS. An experimental case is presented to verify the system feasibility. ©2010 IEEE.

As the rapid development of computer science technology, programs play an important role in our daily life. given a loop program, whether it can finally terminate is crucial for software safety. However, its terminability is normally considered to be undecidable. In this paper, a particular type of program - univariate monotonic loop program is discussed, and by Backward-Iteration approach, their termination sets can be derived. ©2010 IEEE.

In order to support mobile service of long-distance monitoring and controlling UPS based on Web, a kind of design and implementation solution of embedded UPS (EUPS) system is brought forward in this paper. The design and implementation of system is based on ATmega161 and RTL8019AS with TCP/IP protocol suite for communication. In the EUPS system, an embedded file system is designed and implemented which can store the data and index information on a serial EEPROM chip in structured way and communicate with MCU through I2C bus. By embedding the file system into UPS system or other information appliances, users can browse and manipulate local data on the web client side. Based on our experimental tests, the performance of EUPS can meet the requirements of Web-based mobile services. © 2010 Binary Information Press.

In this paper, a control mechanism is presented to improve the compliance performance of the robot manipulator when it is in contact with the unknown environment. This mechanism guarantees that the dynamics of the whole system follows a target impedance model so that the desired compliance performance is obtained. In particular, under the assumption that the dynamics is periodic, a learning law is developed to estimate the unknown dynamics parameters. Besides, the proposed systematic learning control does not require the accurate force measurement. Its performance and robustness are discussed in details by the rigorous analysis. At last, the validity of the proposed method is verified by simulation. © 2010 IEEE.

Depth estimation with a practical camera

Depth estimation with a practical camera

Given an off-the-shelf camera, one has the freedom to move the camera or play around with its intrinsic parameters such as zoom or aperture settings. We propose a framework for depth estimation from a set of calibrated images, captured under general camera motion and parameter variation. Our framework considers the practical trade-offs in a camera and hence essentially generalizes the more constrained areas such as lateral or axial stereo, shape from defocus/focus etc. We discuss practical issues where such an approach becomes important. We pose the problem in a MAP framework and compute the depth estimates efficiently using belief propagation (BP). We also incorporate the visibility consideration to handle occlusions. Moreover, we use the vital cue from color image segmentation to constrain the estimation process. Our results demonstrate the effectiveness of our approach to localize discontinuities and handle low-textured regions. © 2009. The copyright of this document resides with its authors.
