离散余弦变换(D iscrete Cosine Transform )简称D CT,是一种实数域变换,其变换核为实数的余弦函数,除了具有一般的正交变换性质外,它的变换阵的基向量能很好地描述图像信号的相关特征,所以在图像信号的变换中,D CT变换被认为是一种准最佳变换。 -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.
