A method used for extracting multiscale features is applied to the optical remote sensing cloud images.They are decomposed to multiscale space and the features of images are expanded during the process,from which a multiscale feature vector can be acquired.Provided identical feature algorithm and classifier,it is illustrated by experiment that multiscale expanded features can help raise the precision of classification,from which better performance of classifying clouds and earth targets can be achieved.

Key words:  Optical remote sensing images      Multiscale features      Feature extracting      Unsupervised classification
