Discrete cosine transform is also referred to as DCT Transformation . About functions x(n) The discrete cosine transform of can be defined as :
When , And in when ,c(k)=1.x(n) Of DCT The calculation depends on the periodicity of the input signal and on the shaping , Different orthogonal transformation algorithms can be used ( Usually it is DCT1、2、3 and 4), More about DCT For details of the transformation, please refer to chapter... Of this book 6 section .
