This important transform (DCT for short) has originated by [Ahmed et al. 74] and has been used and studied extensively since. Because of its importance for data compression, the DCT is treated here in ...

In this chapter we present a review of the discrete cosine transform (DCT). This is an essential part of the MPEG standard, and must be understood if the reader is to make much sense of the chapters ...

264 and the MPEG standards. At this point in encoding, all the residual data collected during motion estimation is described using the Discrete Cosine Transformation (DCT) method. Initially, ...
