| Abstract: | A novel embedded smart image sensor with situational awareness about outdoor scene is present in this paper. The image analyzing algorithms including foreground detection and shadow removal are based on statistics, and suitable for complex outdoor scene and real time computing. The methods for intelligent video surveillance including crucial area prevention, important target moving detection and camera lens prevention are also proposed. In the implementation of the embedded smart image sensor, the advantages of hardware design are used well. From these testing, it can be seen that this novel embedded smart image sensor is suitable for intelligent video surveillance applications. |
