what is visual attention mechanism?
The visual attention mechanism may have at least the following components:
- the selection of a region of interest in the visual field;
- the selection of feature dimensions and values of interest;
- the control of information flow through the network of neurons that constitutes the visual system;
- the shifting from one selected region to the next in time.
