Structure from motion
Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene.

Thanks @wikitextbot! You are one of my favourite bots (after @haikubot of course).

I am familiar with the general idea but hadn't heard it worded like that. The academic work I do is influenced by much earlier neural models of direction and orientation like Sporns1989:

It's quite a complicated business though, and the papers I've seen that claim to automate the process in some way are quite intense, e.g. Li, Y., Pizlo, Z., & Steinman, R. M. (2009). A computational model that recovers the 3D shape of an object from a single 2D retinal representation. Vision Research, 49(9), 979–991. http://doi.org/10.1016/j.visres.2008.05.013

That looks really cool! "Academic work you do" - cool. Maybe you should do a post on this work? @steemstem is a good place to look for similar and like-minded individuals. Cool video too and hopefully I can find some time to check out the paper too. Looking forward to seeing more of your photography!

You're awesome :)

Thanks! Enjoy the wild ride here...
