The study:
https://www.nature.com/articles/s41559-024-02525-2Sampaio 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]
> [29] Francisco, F. A., Nührenberg, P. & Jordan, A. High-resolution, non-invasive animal tracking and reconstruction of local environment in aquatic ecosystems
Seems it was specifically developed to track fish. Cool project.
