Processing images to extract useful information in real-time is a complex task, dealing with large amounts of iconic data and requiring intensive computation. Smart cameras use embedded processing to save the host system from the low-level processing load and to reduce communication flows and overheads. Field programmable devices present special interest for smart cameras design: flexibility, reconfigurability...
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...
