Reconstruction of a 2D Flat Manifold From Isometrically Embedded 3D Features

The usual problem in multi-view reconstruction consists of estimating the 3D shape of a rigid object from 2D images taken from diferent viewpoints. Of course several other variants of the problem have been tackled, particularly when dealing with non-rigid objects. This seminar will be about reconstructing from 2d images an unknown 2d object isometrically embedded in 3D space.

The best way to imagine it is to think of an image sequence taken of a waving flag. Althought the 2D object (the flag) is the same, at each time instant its 3D embedding changes due to the waving effect.

The intent is to present some preliminary results recently obtained, but the problem is not yet completely solved.
