Hidden information embedded in digital images will inevitably lead to changes in certain characteristics of the image. Research shows that data hiding in the image will introduce the very rich random texture of high frequency component and also cause image noise features change. Thus, a new steganalysis blind detection method is proposed. Firstly, this(More)
We apply previous studied control algorithms to the cooperative target observation (CTO) task for multiple UUVs. The algorithms are based on k-means clustering and hill climbing, and each are scalable in the degree of decentralization. In the underwater formulation of the CTO problem, k-means is not sensitive to the degree of decentralization, while the(More)
