  • Abstract Typhoon is a common nature disaster in Taiwan. However, typhoons also bring plenty rainfall so people in Taiwan do not have too worry about the drought. A strong typhoon will always make a serious destruction in its path. Therefore precise typhoon prediction is very important. The eye of the typhoon and the variation of the temperature change of cloud are important features in the typhoon identification. In this thesis, we analyze the infrared satellite cloud images and extract the features of typhoon in the satellite images. Many researchers used the segmented typhoon cloud images to locate the center of the typhoon. So separation and segmentation of the cloud in the satellite image are important topics in this thesis. Several preprocessing steps are done to facilitate the segmentation of the cloud from the typhoon images. Meanwhile, we present methods that analyzed all the segmented cloud slices based on pixel value and observe the cloud temperature change. Finally, we find the typhoon cloud and locate the center of typhoon according to the difference between the eye of the typhoon and the cloud around it.
