What does N represent here in the basis formula?
$N$ is the length/height of the block. So, for the Y' channel, $N=8$ and for the Cb and Cr channels, it's $16$.
Should DCT be the abbreviation of "discrete cosine transform"?
this video helped me understand the concept better https://www.youtube.com/watch?v=Q2aEzeMDHMA
I've read that the Wavelet transform is used in JPEG2000, how does that relate to the DCT method here?
