The identification of wildfires is a very complex task due to their different shapes, textures, and colours. Traditional image processing methods need manually design feature extraction algorithms based on prior knowledge, because fires at stages have characteristics, designed often insufficient generalization capabilities. A convolutional neural network (CNN) can automatically extract the deeper features an image, avoiding complexity blindness phase. Therefore, wildfire method improved...
