| Abstract: | It is difficult to achieve real-time detection of moving object on embedded CPU, especially under complex background, so it proposes a real-time embedded detection scheme based on Gauss Mixed Model, which uses the improved Gauss mixed model, and simplifies the model. The optimized algorithm on C code level and CPU level has made the model more suitable for embedded CPU, also introduces the realization of the algorithm on the DM6446 platform and the system design of software and hardware. the experimental results show that the system can effectively overcome the interference of external environment change and realize real-time detection and multiple target tracking. |
