Abstract :
In this paper, we present a "visual task" which can be considered as a part of a active vision sensor. This task consists in a tracking of gray levels windows of interest. Our approach is based on an efficient matching between hardware architecture and software algorithm. The notion of active detector is introduced in order to take into account the adaptive and local aspect of the processing. To validate our approach, a high speed tracking method based on a CMOS sensor and FPGA is presented. According to the size of the window, the acquisition rate varies from 200 fr/s to 1000 fr/s
