Abstract

Abstract

The North-west Pacific (NWP) Ocean is one of the places that have the maximal frequency of tropical cyclones (TC) and the highest intensity of TCs in the world.It is significant to investigate the characteristics of TCs in the NWP.Nephogram is an important tool for monitoring tropical cyclone and typhoon in the tropical ocean,effective classification of image data and the segmentation of typhoon cloud are key steps for subsequent image feature extraction.Matching pursuit is one of the most important algorithm in signal processing and of vast application remote sensing image pattern recognition.In the paper,Matching pursuit algorithm is proposed to realize typhoon feature extraction in the NWP.Although the veracity is needed to be improved,the algorithm could efficiency segment the main typhoon cloud systems,and can satisfy typhoon forecast and monitoring well in the meteorological applications.
