This algorithm improves the blemish which is not blind, at the same time it keeps from the block effect which brought in by changing too much of DC coefficients.
该算法改进了在DC系数中大都为非盲水印的缺点，同时避免了DC系数改变过大引起的块效应。
The voltage margin method for interchange power control was applied to the dc voltage control block (DC-AVR) and the active power control block (APR) in the terminal controller.
容压法电力交换控制已经应用于终端控制器的直流电压控制部分和有功功率控制部分。
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。
