Strip Smoke and Cloud Recognition in Satellite Image

Abstract

Forest fire detection based on the satellite image is an important method for fire warning. In the early stage of the forest fire, smoke is a key feature to detect. But both the smoke and cloud are mist shape, which has similar shape. For most smoke satellite image, The smoke is in the shape of a strip, for this feature, an method using edge detection to recognize smoke and cloud has been proposed. This algorithm detect the region covered with mist, and recognize the shape of the mist area using edge detection, to effectively recognize cloud and smoke. More than 30 images with cloud and strip smoke are used to test this method show the method can effectively detect strip smoke.
