We describe a user assisted technique for 3D stereo conversion
from 2D images. Our approach exploits the geometric structure of
perspective images including vanishing points. We allow a user
to indicate lines, planes, and vanishing points in the input image,
and directly employ these as constraints in an image warping
framework to produce a stereo pair. By sidestepping explicit
construction of a depth map, our approach is applicable to more
general scenes and avoids potential artifacts of depth-image-based
rendering. Our method is most suitable for scenes with large scale
structures such as buildings.
