Prediction of cloud for weather now-casting application using topology adaptive active membrane

Abstract

Prediction of meteorological images from a given sequence of satellite images is an important problem for weather now-casting related application. In this paper, we have concentrated on the dominant object of a meteorological image, namely cloud, and predicted its topology within a short span based on currently available sequence images. A topology adaptive active membrane is used to model the intensity profile of the cloud mass and based on a series of such membranes a future membrane is extrapolated under linear regression method and affine shape constraint. The proposed scheme is tested with ISRO satellite (Kalpana 1) images. © 2009 Springer-Verlag Berlin Heidelberg.
