    Oui, je suppose ça ferait une forme pas exacte, mais pas random.
    L'images des cubes par exemple, il y aurait de la symétrie, pas juste un des points qui va n'importe où.

    Et j'imagine la gueule des prompts pour dire de se concentrer sur les points de fuite, difficile à décrire en langage "naturel". Avec un peu de chances ça va pas être facile à corriger.

    @nartagnan @legendarybassoon @grototo @AudeCaussarieu je suppose qu'on est déjà entré dans une nouvelle guerre "génération de fakes crédibles" vs "détection de fakes", comme on a déjà les crawlers/rate-limiter, pub/ad-blocker, tracker/anti-tracker, etc. 😒

    Donc oui, même si ce n'est pas facile (?), je ne serais pas surpris que les entreprises derrière ces générateurs d'images analysent les techniques de détection et fassent leur possible pour les rendre inopérantes.

      @nartagnan l'uncanny valley dans 10 000 ans, si on est encore dans les parages : pourquoi la reconnaissance instinctive des lignes de fuite est devenue un enjeu de sélection naturelle ?

        Mais ça va coûter.
        Même avec de la détection, s'ils veulent faire comme le claude code, aka "génère, on check, et tant que ça passe pas le check recommence, même si c'est 1000 fois", ça va leur coûter... 1000 fois plus cher.

        Et ils n'auront pas ce luxe encore très longtemps.

          @nartagnan en fait, je vois même pas comment intégrer ça au process d'entrainement, sans que cela devienne une machine à gaz, ce qui est déjà le cas however, genre encoder un raytracer

            @FabMusacchio it is really telling that one of the most powerful tools to detect fake images is an artistic tool that any first year art school student knows about

                Ça, ça marchera jusqu'à ce que les IA génératives d'images se mettent à placer les éléments d'une image dans un espace en 3D.

                                    I see that it's commercialised e.g. <https://lovingsquad.com/product/ai-slop-is-not-art-chatbots-are-not-your-friends-shirt/>, <https://pagtee.com/product/t-shirt/1926944-ai-slop-is-not-art-chatbots-are-not-your-friends-cyborg-painting-flames>, <https://zerevia.com/product/t-shirt/1926944-ai-slop-is-not-art-chatbots-are-not-your-friends-cyborg-painting-flames>, <https://www.spellingmistakescostlives.com/product-page/copy-of-ai-slop-is-not-art-chatbots-are-not-your-friends-sticker>, however there's no real acknowledgement of an original artist; no credit, as far as I can tell.

                                        @FabMusacchio So if I want to commit a murder, I have years to prepare it and I know the place will be surveilled with cameras, I should pave it with slightly non-parallell tiles, to get a plausible deniability.

                                        @microblogc @FabMusacchio Forced perspective is your friend: "The Potemkin Stairs in Odesa extend for 142 metres, but give the illusion of greater depth since the stairs are wider at the bottom than at the top."

                                          @nCrazed @f4grx @FabMusacchio But this is irrelevant for the technique described? It would work with a non-parallel spot lamp just as well?
