I wish to participate in upcoming GSOC. I want to discuss couple of ideas.
It would be great if I can have some feedback on these :).

I have described these briefly below. Kindly let me know if further
details/ clarifications are required.

1) Automated rigid structure reconstruction from set of un-ordered images:
A very common structure from motion (SFM) tool, Bundler[1] can be used to
recover 3D point cloud from such images. Its output can
further transformed into dense patches[2] on which schematic reconstruction
can be done[3]. See the video here: <
http://www.youtube.com/watch?v=UwSGtqUZx3M>. Developing this pipeline into
Blender will be a fun project.

2) An interactive tool for 3D modelling: A tool can be made
and integrated into blender as indicated in [4] which uses bundler's[1]
point cloud. They use plane estimation for modelling which is quite
accurate. They have presented a pretty neat and robust way of estimating
planes using points clouds and vanishing points. See the video here:

3)Non-rigid reconstruction (motion capture) from set of static cameras:This
reconstruction is for slightly different domain, mainly motion capture.
This is actually one of the methods I have coauthored[5]. It requires
labelled track points in all the cameras feeds as input. The salient
feature of this method is that it can handle occlusions. This method has
been extensively tested on CMU mocap database.

Reconstruction from this method can be used in motion re-targeting like in
Avator and Pirates of the Caribbean. Including this into blender will be a
great GSOC project.

Kind Regards.
