Abstract: In the article, a study of automatic location of typhoon without eye is carried out by means of GMS infrared cloud images, and a four-step location scheme which includes pre-process of cloud image, interactive segmentation, extraction of shape feature of spiral cloud belt, minimum-average-square-error approach to spiral and center location, is proposed. According to scheme better results are acquired.

- spiral cloud belt /
- interactive segmentation /
- skeleton /
- minimum-average-square-error approach
