Unified Parallel Lattice Structures for Time-Recursive Discrete Cosine/Sine/Hartley Transforms
(1991)
The problems of unified efficient computations of the discrete cosine transform (DCT), discrete sine transform (DST), discrete Hartley transform (DHT), and their inverse transforms are considered. In particular, a new ...
Real-Time Parallel and Fully-Pinelined Two-Dimensional DCT Lattice Structures with Application to HDTV Systems
(1991)
The two-dimensional discrete cosine transform (2-D DCT) has been widely recognized as the most effective technique in image data compression. In this paper, we propose a new algorithm to compute the 2-D DCT from a ...
