I technically released it like a month ago but I only posted about it on twitter, sorry about the trouble! I hope the asset you purchased is much more usable than my stuff.
@@quentinchoumont3437 That one can do way more than just that one filter. So I guess the purchase was worth it (one of the demos looks like Antichamber which is great)
I wasn't super impressed by the effect until I saw the HUGE improvement it makes to FFXIV... it looks like an entirely new game and it's gorgeous. I love it.
I will say that the original Kuwahara filter did a great job for what it was meant to do. Also, as an artist, I use this filter (or it's equivalent) all the time when searching for common colors on an image for either reference drawing or when I'm trying to achieve a 'style'. Great video, just a little offended that something like that would be considered 'not good' xD
I did say they all have their aesthetic appeal! I use the basic kuwahara filter a lot as a pre pass to other effects since it simplifies more than the anisotropic filter does and is pretty cheap performance wise.

Hi Acerola, You mentioned towards the end looking for the Manifold Garden presentation, and I've managed to find one that does outline parts of their anti aliasing techniques. I can't post the link without UA-cam hiding the comment, so the title of the video is "(SIGGRAPH 2020) That's a wrap: a Manifold Garden Rendering Retrospective". Hope this is close to what you're looking for.
I don't even work with computer graphics, but your content is fantastic. So nice to watch the way you evolved the development of the methods and made it enjoyable. A natural gift for teaching.
One of the difficult things in removing noise is deciding which fine objects need to be preserved, like eyes, and which you might want to leave out, like moles.
Moles are not noise. They are facial(or elsewhere on the skin) features exactly as eyes are. Removing those is completely different thing that denoising. Maybe you expect denoise filter to make the boobs bigger, tummy smaller and apply better makeup too?
@@MarcelAndrian What I want my face to look like has nothing to do on using completely wrong tool on the wrong task. But also, I am very content on how I look and I don't have to resort on superficial vanity and lies to hide what ever I might have on my face with faux images of myself. I'm sorry that you don't have such a healthy self-esteem.
You're not alone in wondering how manifold garden did edge detection. I worked on a (now scrapped) project with a similar aesthetic and could never figure it out.
@@SjorsHoukes He's hearted a lot of comments and it is harder to find now but the comment said to search for "(SIGGRAPH 2020) That's a wrap: a Manifold Garden Rendering Retrospective "
I've been trying to get rid of the aliasing in my edge-detection shader for years and I'm still unable to, I thought it was something easy to fix but that I couldn't find for some reason. 😭
Honestly I found the style of these annoying at first but it really grew on me, especially after it becoming abundantly clear that you really know what you’re talking about. Brilliant work, super looking forward to more!
7:12 I spit my cereal, you can't do this to me. I'm shaking, crying, pissing my pants. My fields have been salted, my possessions, stolen, my animals slaughtered.
Loved all the niche references throughout this video, particularly the extensive use of Persona OST for the music and the Monogatari style visuals like the quick frames with either walls of text or "black scenes".
I really appreciate all of your videos. You are great at breaking down difficult to understand problems and have given me a lot more incite on how a lot of visual effects are done. I also enjoy your very dry tone and humor. I am glad to see your channel growing! Keep up the great work!
Great video Acerola. I had implemented a version of the Kuwahara filter in the past, but I had no idea about the history behind it, so thanks for enlightening me :)
Excellent excellent video. Learning a ton from this as a young tech artist on the job. Also desperately trying to optimize a custom postprocessing effect that costs 5ms at the moment…Relating hard to both of your freeze frame rants right now.
Only watched the first 14 seconds but you're right, telling computers what to do just makes up for our own inability to do billions of calculations per second, glad to see someone understand what programming is all about.
I am going to steal "I hope your milk is one day expired" the next time I need a sort-of-but-not-too-threatening insult. Thank you. (Also great video as usual.)
Since UA-cam doesn't like me commenting the link to the Manifold Garden presentation you mentioned, whose researching had cost me hours and was a huge pain to find, I just want to say that I love your videos and want to send you the link to the presentation.
Oh cool! I've been taking an imaging and multimedia class that goes over a bit of stuff like this. I really liked the anisotropic kuwahara filter + dithering, especially the one of the sailor at 14:26.
can I just say I really really really enjoy these videos. It's one of the most youtube series at the moment. I was always curious about post processing effects and adding it in pixel art in particular. Some of my favorite videos on yt
As someone who produces realistic images from blender but wants to simplify detail as an artist, this video was relevant. I also play ffxiv and so was nice. I also make videos and jfc how are you so good. Editing and pacing were great. Hope this blows up big!
Funny, I wrote up a kuwahara filter in shadertoy right around when you released this. Yet if I had seen your video would have implemented paparis color weighting math. The thing I like about kuwahara is that you can get edge values relatively cheep when running the sampling and finding the color deviation. Even tangent values of those edges, for things like embossing effects. All in a single pass through the kernals This is still one if my favorite styles that is basically free in how its set up for everything it can do. The inate style of the noise reduction, so purrrddy!
Nice! Back in 2019 and with no previous knowledge of denoising algorithms I wrote a filter with a similar, yet even less organic look than the box kernel Kuwahara one.
I'm not gonna lie I've been binging all of Acerola's videos because they are so interesting to me as a budding computer science major. I'm not sure if I'm going to end up in a similar field working with graphics like this, but I find it so much fun to learn about all these difference effects and shaders you can add onto images and games, and the math and code behind them. I wish more people knew about this channel!
Wow that's a really informative video! I didn't know when those 18 minutes passed! Since I'm working on a project right now and sometimes get limited by my lack of knowledge about shaders, these videos are amazing! Binge watching more soon! Mentioned you in my last video :))
As someone getting into painting, the Basic Kurosawa filter feels like it'd be good enough by itself. Like, you get rid of some detail off of your reference and then use that easier image to do a painting. But still, the generalized and anisotropic versions look awesome.
basic and generalized kuwahara is actually way closer to many modern oil painting styles imo. anisotropic looks like renaissance style oil paintings, paintings that take very long and try to be as close to a real picture as possible, the other two are far more stylized and actually in my opinion way more recognizable as painterly
such a great video, cant wait to see what it looks like when applied to textures first! edit: im watching it again after watching your final fantasy video because its just that good

Great video! It would be interesting to see if a filter like this could be used for upscaling low res games, specifically The Binding of Isaac Rebirth. It has a built in toggleable filter to make the game more closely resemble flash Isaac, but it looks atrocious, so it would be neat if a more sophisticated filter like this one could actually get the job done.
I'll make a vid on upscaling algorithms someday. I find that the kuwahara does work a little better when you upscale the image first and then filter it but that's to make it more stylized rather than recreating a true upscaled render. iirc the bilateral filter is also used for upscaling a lot, before machine learning upscaling was a thing at least
I got recommended this at random and have zero knowledge of graphic programming, but stayed for the Bill Wurtz-esque vibes. I'm shaken by the sheer amount of math that goes in to making video game look pretty.

what if i had already saved the noise in photoshop?
