Nowadays, with the developing of the computer science, computer vision is widely used in many areas. It is still a major problem about feature recognition in complex background and uneven intensity of light environment. Some researchers have already achieved in particular conditions. With the robot stepping into family, it is necessary to conduct in-depth study about feature recognition and access to information in complex indoor environmental conditions. In this paper, we present a fast identification approach for QR code in the indoor environment with normal light intensity. In the process of image feature recognition, it is very difficult for the edge while recognizing the slope image. Therefore, we use vector method to express the color characteristics in the image, and use the square minimum method to determine the edge lines of the pattern. In addition, linear scale transformation makes the image pattern more suitable for standard grids, which can correct the tiny sampling error. Besides, in the experiment of emulation process, we add a colored periphery features to positioning the image. It can be captured clearly due to the special colored background and behave well in the distance of 0.5m to 2m. Using an 860-pixel distance camera, the QR code pattern can be captured easily and identified effectively. A feedback control planar mobile robot is used as a platform to verify the identification method. After the robot heading to the front of the QR code pattern about 0.5m, the data of the sample image can be scanned and read accurately. The experiment results show that the approach is feasible and effective.

The present book includes a set of selected papers from the seventh "internationalconference on informatics in control automation and robotics"(ICINCO 2010), held in Madeira, Portugal, from 15 to 18 June 2010. The conference was organized in three simultaneous tracks: "Intelligent control Systems and Optimization", "robotics and automation" and "Signal Processing, Systems Modeling and control". The book is based on the same *** received 320 paper submissions, not including those of workshops or special sessions, from 57 countries, in all continents. After a double blind paper review performed by the Program Committee only 27 submissions were accepted as full papers and thus selected for oral presentation, leading to a full paper acceptance ratio of 8%. Additional papers were accepted as short papers and posters. A further refinement was made after the conference, based also on the assessment of presentation quality, so that this book includes the extended and revised versions of the very best papers of ICINCO *** to high quality standards is a major concern of ICINCO that will be maintained in the next editions of this conference, including not only the stringent paper acceptance ratios but also the quality of the program committee, keynote lectures, workshops and logistics.

Session 1 includes 109 papers selected from 2011 3rd international asia conference on informatics in control, automation and robotics (CAR 2011), held on December 24-25, 2011, Shenzhen, China. This session will act as an international forum for researchers and practitioners interested in the advances in and applications of Intelligent control Systems. It is an opportunity to present and observe the latest research, results, and ideas in these areas. Intelligent control is a rapidly developing, complex, and challenging field of increasing practical importance and still greater potential. Its applications have a solid core in robotics and mechatronics but branch out into areas as diverse as process control, automotive industry, medical equipment, renewable energy and air conditioning. So, this session will aim to strengthen relationships between industry, research laboratories and universities. All papers published in session 1 will be peer evaluated by at least two conference reviewers. Acceptance will be based primarily on originality and contribution.

This paper presents the application of Wavelet based State Dependent Parameter (WSDP) models to the identification of a Continuous Stirred-Tank Reactor (CSTR). Here, in order to characterize the process dynamics which is highly nonlinear and multi-variable dependent, 2-D WSDP model is used. The simulation results demonstrate the effectiveness and advantages of the identified model.

In this paper, nonlinear identification of a Liquid-saturated Steam Heat Exchanger using Wavelet based State Dependent Parameter (WSDP) models is presented. This is a highly nonlinear, non-minimum phase process, and often operated under varying conditions. Here, in order to characterize such dynamics, 2-D WSDP model is used. The simulation results demonstrate the merit of the identified model.
