Jsteg and F5 are two typical steganography methods of JPEG images and have been used widely. To distinguish F5 stego images and Jsteg stego images, a classification algorithm based on sensitive features and SVM classifier is presented, where the sensitive features are extracted from the subband coefficients of those stego-images and the subband coefficients are obtained by wavelet packet decomposition...
High spatial resolution remotely sensed images have made it possible for humans to observe the earth in detail; however, there are new challenges for processing such kind of images. Some different categories in the images are always classified into one category using spectral features based classification method, because they have similar color or intensity. In recent years, the image processing approach...
