DCT, or Down the Rabbit-Hole (Part II, Orthogonal)

In the first part of this epic we investigated the substance of the issue and promised to build a

“How Fish Evolve into Squirrels”, now in 3D!

Up to now I’ve tried to put across the fundamental principles of video encoding methods “in hand-waving terms” (I’ve hardly got any more hands to wave now).

DCT, or Down the Rabbit-Hole (Part III, Fourier)

It would be difficult to name an area of science that didn’t apply a Fourier transform somewhere. Fourier’s genius discovered a unique instrument linking the continuous and discrete worlds.

DCT, or Down the Rabbit-Hole (Part I, Correlated)

Until now we have discussed only one aspect of video encoding, namely how to eliminate time redundancy.
