The proposed scheme of this paper is embedding watermark into intra frame (I-frame). The most challenge of watermark that embedded into intra frame is the selection of intra prediction might be changed. In the research, different AC coefficient gets different effect when the selection of intra prediction was changed in another compression course. Therefore, it's necessary that finding what AC coefficients...
By using linear algebraic techniques, this paper proposes a simple approach to derive new matrix bounds of the solution of the continuous algebraic Lyapunov equation (CALE). Both upper and lower matrix bounds are presented. Compared to existing works on this topic, these newly obtained bounds are less restrictive and easier to calculate. A numerical example is also given on order to compare the tightness...
