This project proposes now to link this pre-attentive stage of processing to a subsequent attentive processing stage. It is mainly concerned with the various links towards higher-level vision. The goal set for the next activities is thus to exploit and extend the now available stage of visual attention for performing subsequent segmentation and recognition processes in a prioritized, sequential way, best suited for implementation efficiency.
The recognition system proceeds in two distinct steps. The preattentive step operates under a principle close to visual attention and produces a list of significant spots of attention. Each spot of attention is then analysed separately in a second step of attentive vision.
