Make3D
At least two images for reconstructing a 3D scene is a conventional belief. Yet, we do know that our eyes reconstruct 3D scenes from various single snap shot images, just with one picture. Based on our perception and learning ability or our internal pattern recognition ability, a few groups of people have been trying to reconstruct a 3D image from one still image picture. Luckily you can test such progress, reconstructing a 3D scene from a single still image at Make3D (a click brings you to Make3D at Stanford).
Among thousands of pictures, there are only a few astronomical pictures, a few galaxies and a nebula and reconstructing 3D astronomical scenes from these small number of single still images is disappointing to me compared to other types of images. Astronomers, if you have some images – I’m particularly interested in images of solar activities, though – would you try Make3D? Who knows, virtually you can travel through coronal loops!

Probably, the reason that Make3D did not work well on astronomical images (too small sample size for a generalization, though) is attributed to pseudo colors and the different holistic nature in astronomical images.

Thanks for telling us about zunavision@stanford. I met a few Stanford EE students some years back while I was interning at AT&T Labs (before the split but after Lucent Tech.) and was told quite intriguing and interesting stuffs (I admired them). However, in terms of applying it to natural science, I couldn’t see the real usage of zunavision, except creating space traveling virtual reality. I saw a movie that visualize a travel from the Earth to the outer solar system, and moving along the Milky Way, then passing the local group … I wonder how this video clip that I saw can be improved with your zunavision. I wonder such image implementation seen from zunavision can happen in virtual time as well as reasonable cpu time. Time flow in the universe is unrealistic – even if one travels with the speed of light, to reach the nearest neighbor takes 4.3 years. Please, inform us any zunavision applications associated with astronomy in future. Thanks again!
