The meaningful gray image is serially processed into watermark signal and embedded into the DC elements of the block DCT coefficient matrix of the host image.
该算法是先对有意义的灰度图像进行水印序列化处理后，再将其作为水印信号嵌入到载体图像的分块DCT系数直流分量里。
The results show that occurrence of the single or double pole block on the DC lines, or short-circuit faults on the DC or AC lines will not influence seriously on power system stability.
仿真结果表明：当南桥、华新换流站发生直流输电单双极闭锁以及交、直流侧短路故障时，不会给系统带来稳定问题。
