Pixel-value-differencing (PVD) based steganographic methods, which take into account the characteristic of human visual system, usually lead to large embedding capacity and good visual imperceptibility. In this paper, a recently proposed PVD-based steganography is further studied. First, by deriving a sufficient condition for data embedding/extraction, we show that the method can be generalized, and...
In the South Qinghai Plateau there are problems due to the breadth of scope, complex terrain and disparate climates, and it is important to find ways to increase classification accuracy for broad scale vegetation information extraction. In this paper, vegetation information is extracted by supervised classification combined with division of the whole region into major ecological regions, and vegetation...
