digital painting theory

28 12 2009

i was experimenting with CC effect unit, and i wanted to make the result more softer, more painting like.

the easy way was just to use blur like stuff, but thats not so nice.

but…

but after i had a terrible idea, lets try to involve the ‘optical flow’.

i dont want to describe optical flow with my own words so let me ‘copy paste’ the definition.

Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer (an eye or a camera) and the scene.

ok its very general, so lets focus on the specific one:

The Horn–Schunck method of estimating optical flow is a global method which introduces a global constraint of smoothness to solve the aperture problem.

Master Vade (now we know he is jedi) was the hero, because he made the QC version. The original one is coming from Andrew Benson. And iam very happy to use it!

One interesting twist on using optical flow that can get a similar look to what it seems like you’re getting here is using a pseudo median filter. That, in addition to some feedback loops can be pretty slick.

The v002 optical flow is really a great one!
