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. The effectiveness of this instrument has been proven in theoretical terms as well as in actual practice. A Fourier tranform allows us to see our problem from a new, clearer prospective. Read more >

Practical Motion Estimation (Part II, And Yet It Moves!)

In my previous post we tried to make a deep dive into the anatomy of motion estimation algorithms in video processing. Perhaps a little too deep ;)…
Now, let’s have a look at how it “looks.” I mean literally, how do the motion vectors look? The question is: do motion vectors in the video below trace the handle knob movement trajectory? Read more >
