Abstract

In this paper a special focus on the relationship between sensitivity and stability in a dynamic selective visual attention method is described. In this proposal sensitivity is associated to short-term memory and stability to long-term memory, respectively. In first place, all necessary mechanisms to provide sensitivity to the system are included in order to succeed in keeping the attention in our short-term memory. Frame to frame attention is captured on elements constructed from image pixels that fulfill the requirements established by the user and gotten after feature integration. Then, stability is provided by including mechanisms to reinforce attention, in such a way that elements that accept the user's predefined requirements are strengthened up to be configured as the system attention centre stored in our long-term memory.
