Principal Component Extraction technique is employed to process cloud images from 10-channel radiometer onboard the Chinese FY-1 polar-orbiting meteorological satellites. The results suggest that the consensus technique can concentrate the prominent distribution features of the grey shades of the targets, including clouds, landform and oceans shown on the 10 channel images onto a single image, which can be used as a background image in further synoptic system analysis and weather map overlapping.

Keywords:FY-1, image processing, Principal Component
