discrete cosine transform (D iscrete Cosine Transform) referred D CT it is a real domain transform, transform its nuclear real number of cosine function, in addition to the general nature of the orthogonal transformation, its transformation matrix-vector can be a good image to describe the relevant characteristics of the signal, the image signal transformation, D CT transformation has been seen as a potential best transformation.
