Development of theoretical models of computational attention, to evaluate image fusion methods, as well as to advise advertisers.The human visual system uses different amounts of resources in different locations in the visual field and only those characteristics that are capable of attracting our attention are perceived. Through this line we are developing theoretical models of computational attention that we are using to evaluate image fusion methods as well as to advise advertisers when deciding whether an advertising image is adequate or not based on the level of attention it attracts. what they want to sell or show on the part of the observer.
