Sampaio et al., Multidimensional social influence drives leadership and composition-dependent success in octopus–fish hunting groups
I was curious about the the 3D reconstruction of the scenes.
> We manually tracked individuals in the videos using the software Computer Vision Annotation Tool. We annotated three frames per second, which yielded a time resolution of 0.33 s for animal movement.
> We then used another software developed to incorporate the previously tracked animals in each camera in the ‘colmap’ habitat models and camera paths, ‘multiviewtracks’ or ‘mvt’ [29]

Seems it was specifically developed to track fish. Cool project.

- UncleOxidant 2y agoIt's too bad there aren't more software projects (and jobs) like this.
- AndrewKemendo 2y agoOctopuses don’t have money, so the people with money aren’t interested in putting more resources into understanding octopuses.
- rkagerer 2y agoBut surely if they can punch fish they can click ads?
- tonetegeatinst 2y agoAwaiting the ad industry giants to see this new source of end users.
- glompers 2y agoNew meaning to HN hug of death too
- fuzztester 2y agohee hee x 8 x n. (n is the number of octopi, and 8 tentacles per octopus).
- yumraj 2y agoIt’s sad that you thought you had to explain it.
- fuzztester 2y agoReally? It's even sadder that you felt the need to spend your precious time commenting on something you think is sad.
- patcon 2y agoOy, this just gave me a dystopic angle on a collective intelligence initiative I'm excited about: using LLMs to get non-human entities like rivers on advisory boards. https://x.com/zarinahagnew/status/1815442685446033613 https://x.com/zarinahagnew/status/1815442685446033613 > Voice of Nature - leveraging advanced environmental data, we're developing fine-tuned AI agents that can deliberate on behalf of non-human stakeholders & better represent/surface relevant information about our ecosystems, as a method to improve collective intelligence. The dystopic angle: what if future energy goes into bringing nature into active engagement with capitalism... Hopefully I'm never living in the world where someone has a bridge in Brooklyn to sell and the buyer is the Hudson River :)
- rkagerer 2y agoSome rivers have been granted legal personhood: https://www.nationalgeographic.com/travel/article/these-rivers-are-now-considered-people-what-does-that-mean-for-travelers https://www.nationalgeographic.com/travel/article/these-rive... (with a varying spectrum of exactly what that means).

- rmbyrro 2y agoWait, if I train octopuses to click ads on my website, it's not ad fraud, is it? They're not bots...
