Since the existence of buried targets influences the surface' IR images changing with time,buried targets were detected by multitemporal infrared images.In order to denoise the exposal nioses of partial IR images,a method of kernel minor component analysis(KMCA) was put forward to denoise multitemporal images and overcome the difficulty in choosing images automatically,thus,the good images could be attained automatically.Then a fuzzy kernel cluster algorithm with spatio and temporal restrictions(STKFCM) was...
