A series of computer vision-based fire detection algorithms is proposed in this paper. These algorithms can be used in parallel with conventional fire detection systems to reduce false alarms. They can also be deployed as a standalone system to detect fire combined with a video acquisition device. This paper chiefly discussed the segmentation problem. It adopted the L*a*b*, YCbCr color space an...

The 90,674 wildland fires that burned 2.9 million ha at an estimated suppression cost of $1.6 billion in the United States during the 2000 fire season demonstrated that forest fuel loading has become a hazard to life, property, and ecosystem health as a result of past fire exclusion policies and practices. The fire regime at any given location in these regions is a result of complex interaction...

Forest fires are a common natural disturbance in forested ecosystems and have a large impact on the microbial communities in forest soils. The response of soil fungal communities to forest fire is poorly documented. Here, we investigated fungal community structure and function across a 152-year boreal forest fire chronosequence using high-throughput sequencing of the internal transcribed spacer...

Changes in Earth’s environment are expected to stimulate changes in the composition and structure of ecosystems, but it is still unclear how the dynamics of these responses will play out over time. In long-lived forest systems, communities of established individuals may be resistant to respond to directional climate change, but may be highly sensitive to climate effects during the early life st...

The Mediterranean countries like many world countries have forest fire problem. Many forest fires have occurred each year and huge amount of forest areas in each country have been lost. 27% of Turkey’s lands are covered by forest and 48% of these forest areas are productive, however 52% of them must be protected. There occurred 21000 forest fires due to several reasons between 1993 and 2002. It...

Forest fire control is a challenging research problem involving a non-stationary environment and multiple cooperating agents. In this paper we describe the application of enforced sub-populations (ESP) to evolve neural network controllers that solve different instances of the forest fire control problem. Our system works by initially generating subgoals and assigning subgoals to the different a...

Resume-This article shows the most usual fire detection and forest extinction application technologies at present. We will see all different methods used by these applications that can be found in the Market and some examples. Also, some basic questions about the most influent parameters when a fire must be extinct are shown. Finally, after having shown all the technologies, we will build a mod...

The most important parts of protective and observe systems are the fire detection systems. Fire detection is very significant for the safety of the people. In past there were many methods used in forest fire detection. This paper presents a new type of system which uses Un-manned Aerial Vehicle (UAV), wireless technology and power of artificial intelligence for forest fire detection. The unmann...
