Abstract

To be implemented on an analog CMOS image sensor, a robust algorithm based on recursive operations is presented. It allows sensor´s acuity adaptation to the scene activity. The main interest of the presented motion detection with adaptive thresholding is that, in a context of embedded steady camera, such a system allows focusing on targets with high resolution while keeping background in low resolution. Drastic power consumption reduction is achieved by tremendously reducing the amount of processed data.
