Based on introducing overlapping base matrix, the general calculating formula for the coefficientvector of windowed all-phase equivalent FIR filter is proposed.
在引入重叠基矩阵的基础上,提出了加窗全相位等效f IR滤波器系数向量的计算通式。

At first, it quantizes the image coefficientvector gotten from DWT with the lattice vector quantization technology, then imbeds the watermark signal into the coefficient.
Firstly, the image is projected on to the orthogonal basis of SVDQ, then the projection coefficientvector is used as algebraic feature of image and applied to recognition.
