Generally, accuracy of GPS(Global Positioning System) is higher than that of cellular network. But in tall building urban area or indoor, relatively weak GPS signal makes the posi...
We will consider balanced directed graphs, i.e., graphs of binary relations, for which the number of inputs and number of outputs are the same for each vertex. The commutative diag...
Perceptual transparency and robustness are conflicting requirements. To ensure the security of the watermarkhow to choose the embedding position and intensity is a difficult probl...
