- Finally, it comes full circle.
I put a lot of effort into the subtitles. Let me know if they are off at all.

For those who care, in the first iteration of this video, I used a dense optical flow algorithm to show the movement of the edges in the video, with colors corresponding to the direction and the brightness corresponding to the speed. I initially planned to simply make the "movement only" effect, where only the moving edges were visible. But once I got that working, I realized it wasn't very fun to look at alone, so I layered it over the source video with the blending mode "difference".
This second iteration expands on the concept by observing that there is a tradeoff between detecting fast/slow motions and the corresponding blurriness of the motion field. The larger the "window size" is, the larger the motion that can be detected, but it will just be a huge fuzzy region that is roughly the right shape. The smaller the window size, the finer the motion it can detect, but the motion is detected in smaller regions, leading to a less blurry image with sharper edge highlighting. Choosing one window size made some elements look good, but then the tracking on other elements wouldn't work. And often things that changed sizes (like the petals) lost tracking as they moved, because the speed of movement was changing.
My solution was to actually run the optical flow calculation 7 times for every single frame, each time with a progressively larger window size. Then, I layered each of the 7 motion frames together with a lighten effect, which produced the robust composite motion tracking image you see here.
Speaking of the video, for this one, I myself used AI to upscale the source video from 360p to 4K (waifu2x), and also to interpolate from 30fps to 60fps (RIFE). This was crucial for good motion tracking. You can download those upscaled files at the archive page I linked above. - Krátké a kreslené filmy
Literally me when someone asks me to picture an apple in my head
Im mean its not wrong
Its just a "bad" one, but still an apple
@@jineteporcinor.k.3050this wasn't even supposed to be a pun lmao
It's called aphantasia. I have it too
@@BootLegAidan Aphantasia is when you can't picture anything at all tho
@@veradistheeggcat229 aphantasia is the difficulty of picturing something. If it looks like what this video looks like, that's a form of it
“Keep absolutely still. Its vision is based on movement.”
bro created what dreams look like
me when i capture a sci-fi predator and show it human culture
"Bad apple but you're a T-rex"
LMAOOO THAT ACTUALLY WORKS
That also applies for squirrels 🐿 🐿🐿🐿🐿🐿🐿🐿🐿🐿🐿🐿🎻🐿🐿🐿🐿🐿🐿🐿🐿🐿🐿🐿🐿
You know it's not how T-Rex's eyes work, right?
@@Yegor_Mechanic It's a joke, genius.
@@r.henryjr.1533he knows, genius
2:59 looks amazing
This is what the dog in undertale that can only see moving things see
this one so much nicer to look at then the previous one
Looks like light sticks but my glasses aren't on
In the dark ofc
underrated as hell
so this is how that smoker undertale dog sees the world!
I wanted to know this too
I feel blind watching this
I forgot how weird the song text is
Super cool!
Bug did better than real one
This is so cool. It almost looks like how it looks to picture something in your “mind’s eye”
How come everybody else's brains can fully picture this song in their heads but MY brain can only manage this on a good day.
This is basically my vision with myopia
YOU FIXED IT!
YAAAAAAAA!
When it said "can only see the movement", I was expecting to only see the motion blur/afterimages that follow the movement, with the main body(ies) being totally imperceptible beyond that, and instead, I got blurry outlines. Actually kinda disappointed, ngl.
duh
@@question33303 I get that the "sight" of movement would encompass all edges of the thing that's moving, I was just expecting it to only be one edge because I was hoping to see something nearly incomprehensible, not what I usually see without my glasses
@@anonymousapproximation8549 hud
But they aren't blurry outline though, they are the differences between each frames of the animation got filled in. The main body would be invisible if it doesn't move. However, the body does move so you do see an "outline".
@@2EntireLegs considering that there's rarely a point in the animation where it's _not_ moving, then for all intents and purposes, it might as well be just a blurry outline.
take LSD and watch this vid
is it just me or is this make some what tiresome to look at ? cool work but it hurt my brain little
