This paper proposes a novel visible watermarking scheme that is based on dynamic images and preserves context integrity. In our approach, the watermark is divided into many sub-watermarks, and then we utilize the visible watermark method to hide the sub-watermarks into difference images. When the dynamic image with the hidden watermark is done, the human(More)
Soils in the alpine grassland store a large amount of nitrogen (N) due to slow decomposition. However, the decomposition could be affected by climate change, which has profound impacts on soil N cycling. We investigated the changes of soil total N and five labile N stocks in the topsoil, the subsoil and the entire soil profile in response to three years of(More)
