The Extracting of Multiscale Features of Remote Sensing Cloud Images Based on Gaussian Pyramid

ZHOU Quan,ZHANG Rong,YIN Dong(Information Processing Center,University of Science and Technology of China,Hefei 230027,China)  
A method used for extracting multiscale features is applied to the optical remote sensing cloud im-ages.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.
