Euch allen einen schönen Dienstag. 🙂
HabrНаш «домашний» НИИ обошёл DINOv2, ViT и десятки ML‑моделей в сегментации видео
Мы открыли и разрабатываем новый способ обработки информации - TAPe (Theory of Active Perception, Теория активного восприятия). Работаем над ней давно, результаты мягко говоря впечатляющие, постепенно начинаем ими делиться. Немного писали о Теории на Хабре здесь . Исторически мы начали именно с обработки видео (когда-нибудь об этом расскажем). В этой статье покажем результаты сравнения разных методов обработки видео (гистограммы, Фурье, структурной похожести, ML-модели) и TAPe в задаче сегментации видео. TAPe в области компьютерного зрения - это Майк Тайсон и/или Майкл Джордан среди любителей (хорошо, еще не Майк Тайсон, но уже вполне себе Рокки Бальбоа). На фоне методов Теории даже супер прокаченные модели на стероидах растерянно сидят в углу ринга. (Ладно, пока что это все влажные мечты, мы даже еще не вышли толком на ринг; но, как мы помним, главное – это величие замысла). Читать как лажают ML с видео

These two artists always blow me away.
I imagine them both as very raw, in-the-flesh painters, "paint will be needed," "acquire paint for this expression," and so on.
It was always going to come out, the use of paint, no matter what, one way or another. from them.
I saw af Klint's show at Tate a little bit ago, it was one fantastic achievement after another, drawings, prints, etc.
I don't recall being taught very much about these artists in school. It was always straight to Kandinsky, and also always straight to Pollack, depending on what period you were studying.
Female artists were always taking care of kids, and didn't have it in them to hang out at bars all night and get drunk with painter buddies, 5-7 nights a week.
But anyway, the teaching I got from school was usually "only the French school," and what not. Excuse.
The ideas were definitely in the air though, I imagine all over.
Anyway, I think both these painters were incredible in many different ways and for so many reasons.

Filip RachůnekHi everyone! Do you remember the video about detecting edges using the #Sobel operator, which we enhanced by using #Gaussian blur? One of the drawbacks of Gaussian blur is that it's somewhat computationally intensive, which can pose some performance issues for our game if we want to apply such an #effect in real-time. In this video, I will demonstrate a much faster way to #blur our sprite or the entire screen. #Godot #Godot4 #GodotEngine #GodotTips #devlog

Godot 4: Glass Door shader (fast blur tutorial)
marcelo 🇵🇸🇮🇱🕊️O Projeto #Brasil: Nunca Mais desenvolvido por Dom Paulo Evaristo #Arns, Rabino Henry #Sobel, Pastor presbiteriano Jaime Wright e equipe, foi realizado clandestinamente entre 1979 e 1985 durante o período final da #ditadura militar no Brasil, no ano de 1985, e gerou uma importante documentação sobre a história do Brasil.[1][2][3]
Sistematizou informações de mais de 1.000.000 de páginas contidas em 707 processos do Superior Tribunal Militar (STM) revelando a extensão da repressão política no Brasil cobrindo um período que vai de 1961 a 1979, atualmente constituí-se no fundo mais pesquisado do Arquivo Edgard Leuenroth na #UNICAMP em Campinas.
O relatório completo, resultado do esforço de mais de 30 brasileiros que se dedicaram durante quase seis anos a rever a #historia do período no país, reescrevendo-a a partir das denúncias feitas em juízo por opositores do regime de 64, bem como o livro publicado pela Editora Vozes, no dia 15 de julho de 1985,[4] tiveram papel fundamental na identificação e denúncia dos torturadores do regime militar e desvelaram as perseguições, os assassinatos, os desaparecimentos e as #torturas, atos praticados nas delegacias, unidades militares e locais clandestinos mantidos pelo aparelho repressivo no Brasil.
Hi everybody! It is January 2024, I wish everyone a happy new year, and I'm back with new videos from the world of #Godot, #shaders, and I'm also planning to record something about modeling in Blender. Anyways, the first video of this year is dedicated to a shader that can be used for interesting post-processing effects and uses the #Sobel operator along with other algorithms, such as #Gaussian blur. Let's dive into it. #GodotEngine #godot4 #GodotTips #devlog

Godot 4: Edge detection shader (tutorial) - Sobel operator and Gaussian blur
claudeWorking on my #bot to explore escape-time fractals, rendered with distance estimator colouring using my #et project. It's a #bash script that calls out to #ghc #haskell for calculator functionality, plus image fitness function in custom #C code (using #openmp for #parallel processing).
Flatness of #directionality #histogram seems to be a good #metric to add into the #fitness function for exploring #fractals algorithmically, because stretched/skewed images will have strong directionality peaks, while more #isotropic regions will be flatter.
I implemented it using 5x5 #Sobel filters as suggested on the #ImageJ website. Nothing fancy (like Earth Mover's Distance, which I haven't figured out for circular arrays yet) for the histogram comparison, just Euclidean vector distance.

Directionality
This plugin is used to infer the preferred orientation of structures present in the input image. It computes a histogram indicating the amount of structures in a given direction. Images with completely isotropic content are expected to give a flat histogram, whereas images in which there is a preferred orientation are expected to give a histogram with a peak at that orientation.
