The Discrete Cosine Transform

The discrete cosine transform (DCT) is similar to the discrete Fourier transform, but describes signals as weighted sums of cosines rather than weighted sums of complex sinusoids. An advantage of the DCT is that the weights are real valued. The DCT is most often used in compression applications such as MP3 and JPEG.
