in different development stages. We could not automatically recognize the typhoon clouds in all stages based on these features. During different development stages
ty-phoon all has helicity and non-typhoon has no helicity. Based on this
we extract boundary information of clouds and statistics of the rotation degree of boundary clouds in single satellite image. In this paper
we use curvature curve of Bezier histogram to ob-tain two segmentation thresholds
iteratively segment the satellite image
and combine typhoon’s geometric features
such as ro-tation
area and shape to recognize the typhoon. Experimental results show that the typhoon can be recognized effectively in all different development stages.
