Crowd analytics is becoming a highly desirable feature of Intelligent Video Surveillance (IVS) applications. In this paper we propose a new, practical approach that adds very little computational and configuration overhead to an IVS system. The approach extends a standard IVS system, using available video content analysis data and camera calibration information to provide accurate human count estimation in crowded scenarios. The algorithm is viewpoint independent and requires no training for different camera views. The primary output of the algorithm is a real-time crowd density measurement at each image location. This can be further used to detect various crowd related events. Extensive experiments show that the approach is robust and it has been integrated into a commercially available IVS system.

Detecting stationary objects, such as an abandoned baggage or a parked vehicle is crucial in a wide range of video surveillance and monitoring applications. ObjectVideo, the leader in intelligent video software has been deploying commercial products to address these problems for the last 5 years. The ObjectVideo VEW and OnBoard system addresses these problems using an array of algorithms optimized for various scenario types and can be selected dynamically. This paper describes the key challenges and algorithms, and presents results on the standard i-LIDS dataset.

On 12th, January, 2005, the National Department has approved Beijing¡s new city plan (2004¡ 2020), in which there is a remarkable change of the capital¡s developing direction, i.e. building a residential city for more than 18 million population. We had made 8,000 questionnaires during the summer of 2005, and we also had built a database in GIS, and based on the subjective evaluations of the local people¡s, we have calculated the primary results of 100 questions in each questionnaire. By the comprehensive processing of the data and the results, we can concluded that there are some favorable regions in Beijing City¡s now, mostly are around the 4 main circle roads of urban, and along the main rivers and waters in the city, for the new city plan has decided to develop the new satellite city in the sub-urban, and these traditional less developing areas are now becoming the hot spots in the coming years. At last, we construct GIS spatial database for the analysis of Beijing¡s inner spatial residential environment, and its affects on the living style and daily behavior of local citizens. And our research objective was meant to put forward some useful proposals for the capital city¡s construction and the theory of China¡s building harmony society.

Based on the regionalizing zones, districts, and the regions in western China, this paper elaborates the main characteristics and the problems of every eco-economic zones, districts, and regions, which are all based on the GIS analyst and the comprehensive geographical statistic analyzing, we list the main indexes used in the regionalizing and the results to show the main character of each region, which comprise precipitation, temperature, primary production potential, while the population carrying capacity, and the index of water resources, land resources, landscape degradation, urbanization, and economic development, etc. To each type of eco-economic region, we analyze respectively from the social, economic, and natural environment aspects. The result shows that there does now have serious economic development in western China, while the environmental problem still cannot be ignored.

As a modern and international urban, the capital city of China, Beijing's developing has been seen by all over the world. Now the city's developing direction has been denied in the core aspects like residential, political, and culture by the central government, rather than the economic only in the traditional way. This paper is focusing on the research of the development of real estate in Beijing from 1990s, especially the areas of less developing area, which are the main obstacles of Beijing city's developing during the 11th five-year-planning. Using the questionnaire and GIS & RS spatial analysis method, we investigated more than 200 spots in the central city, the 8 districts of Beijing, to collect the field information of these areas. In most of these areas, there live the local people more than 100 years who are mostly the poor, it is the main task of harmony society's to resolve these person's living condition for improving their welfare. Following the new city planning instituted in 2005 by local government, we proposed several suggestions for these less developing areas, i.e. protecting the historical culture, mining the potential values, building new houses for them in the suburban, etc. and there must be other matched politics for reach these purposes.

Multi-resolution techniques have been used in a wide range of vision applications. Unfortunately, the costly operation of building a proper pyramid strongly reduces its value as a tool for reducing computational cost. A new approach, physical panoramic pyramid, is introduced in this paper. Physical panoramic pyramid measures multiple resolutions simultaneously resulting in multi-resolution panoramic images. No computation is needed to construct these image pyramids. We also analyze general noise sensitivity in image pyramids, including the interaction of the loss of resolution, random background noise and aliasing noise. The paper also discusses the issue of indexing between the neighboring layer the viewpoint variation and the applications of the physical panoramic pyramid.

Recently, S. Nayar (1997) introduced a parabolic imaging system that has a field of view of a full hemisphere or more. When used with a video camera the result is an omni-directional video stream that captures everything going around it. In the VAST Lab at Lehigh, we have been experimenting with these cameras, developing new variants, and developing omni-directional vision applications. We present an overview of omni-directional imaging and then two of our applications which we will be demonstrating. The first application is a frame-rate multi-body tracking system. The system uses an omni-directional imager and a standard PC to track multiple moving objects in all directions. The system is designed to provide perspective views of the most significant targets, either locally or over a network. The second application is something we call Remote Reality, which provides an immersive environment via omnidirectional imaging. It can use live or pre-recorded video from a remote location. While less interactive than traditional VR, remote reality has important advantages: there is no need for "model building" and the objects, textures and motions are not graphical approximations.
