- In the realm of image based edge detection, aesthetically pleasing edges are hard to come by. But, what if we could get stylized edge lines by just blurring our image twice?

Thanks for watching!
This video is dedicated to my friend, Alotryx.

This channel produces consistently entertaining educational videos that feel like total shitposts and I couldn't ask for more
This is the difference of gaussians
Randomly changing cross hatching direction in real time every frame (or every few frames) might give you an animated look, like its being redrawn or something
When you randomly come across a tech channel... Dig the presentation style and watch more... Only to find one of your old papers being the topic covered in the video 🤯 The pronunciation of my name leaves something to be desired, but the rest of the explanation and delivery was something I only wish I would've had the skills or time for back then! Super well done 👏Keep up the good (and entertaining!) work
I think this might be the difference of Gaussians
This video, particularly the edge tangent flow and line integral convolution, helped me out a tremendous amount with my job, and led to a breakthrough in a problem I was working on. This is particularly surprising, considering my work has nothing to do with video filters - but it's not an exaggeration to say this saved me weeks, maybe months, of fumbling around. Thanks mr aceroller :)
I feel like some of these DoGs could make a cool horror game setting, the high contrast could lead to interesting atmospheres
if you had a quantum computer, you could try all variations of the parameters at once, and then use the quantum reverse fourier transform to extract the one that you think looks the best using a neural network trained on your preferences
Incredible, you made me interested in signal processing after 2 teachers bored me to death with it
I wish Taylor Swift would get her alternative phase already
Acerola: as you can see, the fine detail gets preserved
Finally, a video that explains what the D.O.G. doin'.
You are absolutely crushing the dead center of the "wildly entertaining meets comprehensively informative” Venn Diagram🙌
This is top tier content. I'm eternally grateful for a great knowledge you've provided Acerola. I can't stop thinking of an infinite possibilities this technique provides
The intersection between art, math, and computer science here is amazing.
i think it'd be super cool to use the vector flow field to drive the rotation for the crosshatching texture, with the first and darkest layers being parallel to the VFF and the additional layers being varied parpendicular angles rather than random rotation. This would give you a more accurate crosshatching pattern that takes form into account rather than just using raw values.
I love those references to Tatami Galaxy and Monogatari in the editing of the video! Also the topic is presented in a very clear way, it really makes me want to code it up myself
"in signal processing" triggered my fight or flight
Love the references to Monogatari series and Tatami Galaxy! And love the use of Persona music too!
What a banger video! Not only did you manage to reteach me complicated topics I had encountered in a more intuitive way, supported by examples, but also you manages to sustain the feel of a casual conversation throughout. What a video. Subscribed.
