由于水印为8bit的图像，所以对于置乱后的水印分辨率层G2、L1和L0，经位分解操作后都有8个位平面，嵌入函数首先计算出HL3（图2-3所示）中能嵌入G2位平面的个数，如果个数大于或等于8，则将位平面全部嵌入到HL3中；否则HL3和LH3中分别嵌入4位平面，在嵌入过程中需对位平面嵌入的位置作准确的计算。L1和L0位平面的嵌入算法与G2相同。-Since the watermark for 8bit images, so the scrambling of the watermark after the resolution of layer G2, L1 and L0, decomposition by-bit after the operation has 8 bit-plane, embedded function first calculated HL3 (as shown in Figure 2-3) in G2 can be embedded in the number of bit-plane, if the number of greater than or equal to 8, will be all embedded into the bit-plane in HL3　otherwise HL3 and LH3, respectively 4-plane embedded in the embedding process of the need for bit-plane embedded in the location of for accurate calculations. L1 and L0 embedded bitplane Algorithm and G2 the same.
