ABSTRACT
In many modern fields, moving target detection are showing its important role. Especially nearly twenty years of rapid development of social economy, the moving target detection has shown its importance, in various aviation, communication, navigation and so on have a key role, so the study of moving target detection method has become a research hot topic in countries.

By reading relevant papers, a large number of journals and cyber source, understand the basic principle and thought of Gauss background modeling and updating the background. In this paper, firstly introduces the basic knowledge of moving target detectio
n method, such as the two values image, morphological image processing, color space model. Then focus on the study of three methods used for moving object detection, a brief description of the basic ideas of the three kinds of research methods. By the experiment, the results of three kinds of method of moving target detection has advantages and disadvantages, this paper emphatically explores Gauss background modeling and background updating basic principle and thought.
Finally, through the program and software related to mixed Gauss background model for the relevant experiments, and found the shortcomings, the presence of mixed Gauss background modeling algorithm such as: the problem of computing Gauss background modeling, moving target volume larger detection effect is poor, and on these problems put forward relevant ideas and improvement.
