Abstract :
A new algorithm for the computation of a 2-D DCT is presented, the computational complexity as measured in terms of the number of multiplications and additions is kept to a minimum, the algorithm is amenable to implementation using field programmable gate arrays (FPGAs). An example of a 4×4 2-D DCT is presented, and its performance is evaluated
