Answer» The NXN cosine transform c(k) is CALLED the discrete cosine transform and is DEFINED as C(k) = 1/_N , k=0, 0 _ N _ N-1 = _ (2/N) cos (pi (2n+1)/2N 1_ k _ N-1, 0_ n _ N-1 The NXN cosine transform c(k) is called the discrete cosine transform and is defined as C(k) = 1/_N , k=0, 0 _ n _ N-1 = _ (2/N) cos (pi (2n+1)/2N 1_ k _ N-1, 0_ n _ N-1

Answer»

The NXN cosine transform c(k) is CALLED the discrete cosine transform and is DEFINED as

C(k) = 1/_N , k=0, 0 _ N _ N-1 = _ (2/N) cos (pi (2n+1)/2N 1_ k _ N-1, 0_ n _ N-1

The NXN cosine transform c(k) is called the discrete cosine transform and is defined as

C(k) = 1/_N , k=0, 0 _ n _ N-1 = _ (2/N) cos (pi (2n+1)/2N 1_ k _ N-1, 0_ n _ N-1
