Hi,

I am currently studying DCT, and I am curious about what parameters can be tuned in DCT for performance, unlike DC.
I'd be grateful if you let me know anything that comes to mind.

Thank you.

Discrete Cosine Transform needs an input array and a transform coefficient matrix... I guess you are asking for the values of the coefficient matrix. It depends upon which DCT you are using.
For an N-Point DCT, you can refer to the following paper: (They have given the coefficient matrix as well)

Thank you for answer.
But I I made the mistake of not writing down DCT's full name.
It is Design Compiler Topographical (DCT) mode.
I'm really sorry and thank you for your time.
