Assignment 5: Tour Into the Picture: Single View Modelling
- Nisarg Vyas (nisarg

The goal of the project is
to estimate simple 3D geometry model from a single image based on some cues
input by the end-user, and using that 3D model to generate novel views of the
image. This uses the TIP (Tour Into the Picture)
interface first, which allows users to input back plane and the vanishing point
in the scene.
Results:

Sample novel views generated from the original
These
are just 2 sample views from many possible views. To generate even more views,
you can use SJerome_model.fig
, which is a Matlab figure file consisting of the
estimated 3D model of the taken photograph. One can upload that in Matlab, and using the camera toolbar and 3D rotation
properties, one can then generate interesting novel views.

geometry
Sample Novel views
In
the second novel view, we can easily see, that the same
pillar on the upper right corner of the image is shared between the back plane
and the side plane, and hence creating geometric illusion in perception for
humans.
