The non-eye typhoon center locating with parallel computing

A new mathematical morphology-based algorithm is proposed to achieve automatic center location of noneye typhoon. The center of a noneye typhoon is near the geometric center of the cloud system and has higher temperature. For each infrared satellite cloud image, the locating procedures are as follows: a) noises filtering, b) main cloud systems segmenting, c) center locating and d) multispectral image verification. The algorithms are based on operations of mathematical morphology, and designed in IBM SP2 massively parallel computer. The experiment results show that the algorithm locates the centers of most noneye typhoons successfully and achieves faster, more precise and nonhuman interactive noneye typhoon center positioning.
