Abstract
Displaying panoramic and wide angle views on a flat 2D display
surface is necessarily prone to distortions. Perspective
projections are limited to fairly narrow view angles. Cylindrical
and spherical projections can show full 360° panoramas,
but at the cost of curving straight lines, interfering with the
perception of salient shapes in the scene.
In this paper, we introduce locally-adapted projections.
Such projections are defined by a continuous projection surface
consisting of both near-planar and curved parts. A simple and
intuitive user interface allows the specification of regions of
interest to be mapped to the near-planar parts, thereby reducing
bending artifacts. We demonstrate the effectiveness of our
approach on a variety of panoramic and wide angle images,
including both indoor and outdoor scenes.
