data hasnt been embedded in dc coeffs,therefore results in a better histographic response.unlike methods like jsteg where quantized coeffs wid value 1 are not altered because they can be made equal to zero,here they can acquire a value of -1,instead.

As large enterprises, there a lot of emotional load, power grids need to absorb the large number of non-functional capacity, the electricity sector in order to save power and improve the quality of power, the need for reactive power compensati
