Based on the meaning of object state in tracking theory, a novel representation for object state is proposed, which differs from traditional one with only locomotors state. In this thesis, model parameters may also represent the object state in according to different situations. Thus, the localization and characters of object are filtered synchronously, which accelerates the matching and tracking speed in real-time tracking system, especially for complicated object. In summary, this thesis studies the methods of template obtaining, updating and matching, etc.

从跟踪理论的目标状态所表示的意义出发，提出了将目标模型参数与运动参数同时作为目标状态进行滤波的方法，改变了传统方法中只利用目标运动状态的情况，在确定目标位置的同时能够匹配目标轮廓或其他特征，对于复杂的目标，可以快速鲁棒的完成视频帧中的模板匹配和跟踪。

Through analysis, the thesis thinks that the economical nature of environment goods cannot be generalized by public goods or private goods, its nature has been changing between the two extremes. The environment goods is on one hand reflected in some legal arrangement in international environment statute, where the focus is the whole humankind, for example,"common heritage"; on the other hand, it is also reflected in the rules that protecting private rights in civil legal system, where the focus is the individual, for example,"the right of environment personality ". The essential part of environment justice is the social distribution of environment benefits and burdens, so the thesis centers on the social peculiarities of environment goods as social burdens and as social benefits. In detail, environment benefits are related both to property and to personality, and they are also un-produced, non-substitutive and prima goods as living resources; environment burdens are composed of LULUs and many uncertain and irreversible environment risks.

通过分析，本文认为环境物品的经济性质不能单纯地用公共物品或私人物品进行概括，其性质在此两极之间会发生变动；而法律构造中的环境物品一方面体现在国际环境法中的主要以&类&为主体的各种制度安排中，例如&人类共同遗产&，另一方面则体现在民法体系中以&个人&为主体的各种私权保护的规则中，如环境人格权等；接下来，鉴于环境正义的核心是环境利益与负担的社会分配，所以本文重点探讨了作为一种利益和作为一种负担存在的环境物品的各种独特的社会属性，具体而言，环境利益具有财产属性、人格属性、非制造性、不可替代性以及作为生存资源的前提性；而环境负担则具体包括&不可欲的局域性土地利用方式&和具有科学不确定性和不可逆性的环境风险。

A new study idea that makes the occupant injury prevention research and CAD/CAE technology on an integrate mathematical model by means of feature theories and feature design technologies was brought, and it is maybe useful if we study automobile passive safety on a new view of point.The conclusions of this thesis included that what are the main factors of airbag-related injuries and the preventive measures, based on the research of the relationships between injury parameters, such as HIC, chest acceleration, neck force, neck moment, femur axial force etc, and impact speed, belt-use, occupant size (50th and 5th), sitting position and so on. The thesis evaluated whether the effectiveness of the airbag can be increased by making the airbag adaptive to the crash conditions, and points out that the size of the ventilation hole has the dominating influence on the performance of the airbag and is a key factor for intelligent airbag, multi-stage and lower-power inflator can cost effectively minimize the risk of injury to occupants from crashes. It is important for the researchers of intelligent airbag to keep the small size unbelted occupants in focus and it is necessary to study deeply the influence of airbag fold patterns and the extremity out-of-position situation. These topics are important in the study of occupant injury prevention and vehicle safety design.
