Wildfires are natural risk phenomena that cause significant economic and environmental damage. In wildfire fighting strategy it is important to detect the wildfire in its initial stage and to apply, as soon as possible, the most appropriate fire fighting action. In both cases wildfire monitoring and surveillance systems are of great importance, so in the last decade the interest for various wildfire monitoring and surveillance systems has increased, both on the research and the implementation level. This paper describes one such system named iForestFire. It is an example of advanced terrestrial vision based wildfire monitoring and surveillance system, today widely used in various Croatian National and Nature Parks and regions, but it is also a system in constant development and improvement, both on theoretical and practical level. This paper describes its last improvements in video detection part that are based on notation of observer, cogent confabulation theory and mechanism of thought. Inclusion of cogent confabulation theory allows us to expend the use of existing wildfire observers to more general natural risk observers.

“…Under such a formal definition, perception is very much an act of inference. Indeed, it is becoming increasingly popular to think of perception as an inductive inference (i.e., as an inference whose premises do not logically force its conclusions), that is appropriately modeled using Bayesian statistics (e.g., Bennett et al 1996;Freeman 1996;Knill & Richards 1996). Such an approach has been used profitably to provide formal theories of many visual capacities (Brainard & Freeman 1997;Bulthoff & Yuilee 1991;Freeman 1994;Richards et al 1996;Singh & Hoffman 1998).…”

We offer an ecological (Gibsonian) alternative to cognitive (im)penetrability. Whereas Pylyshyn explains cognitive (im)penetrability by focusing solely on computations carried out by the nervous system, according to the ecological approach the perceiver as a knowing agent influences the entire animal-environmental system: in the determination of what constitutes the environment (affordances), what constitutes information, what information is detected and, thus, what is perceived.
