<div align="left"><font face="Arial"><span style="font-size:10pt">Video mosaicing is commonly used to increase the visual field of view
by pasting together many video frames. Existing mosaicing methods
are effective only in very limited cases where the image motion is
almost a uniform translation or the camera performs a pure pan.
Forward camera motion or camera zoom are very problematic for
traditional mosaicing. </span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">A mosaicing methodology to allow image mosaicing in the most
general cases is presented, where frames in the video sequence are
transformed such that the optical flow becomes parallel. This
transformation is modelled by a projection of the scene into some
manifold. </span></font></div>
<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">Manifold projection enables to define high-quality mosaicing even for
the most challenging cases of forward motion and of zoom. In addition,
view interpolation, generating dense intermediate views, is used to
overcome parallax effects. </span></font></div>

<div align="left"><br/>
</div>
<div align="left"><font face="Arial"><span style="font-size:10pt">In this paper, we present a new method for automatically and efficiently
generating stereoscopic mosaics by seamless registration of images
collected by a video camera mounted on an airborne platform. Using a
parallel-perspective representation, a pair of geometrically registered
stereo mosaics can be precisely constructed under quite general
motion. A novel parallel ray interpolation for stereo mosaicing (PRISM)
approach is proposed to make stereo mosaics seamless in the
presence of obvious motion parallax and for rather arbitrary scenes.
Parallel-perspective stereo mosaics generated with the PRISM method
have better depth resolution than perspective stereo due to the
adaptive baseline geometry. Moreover, unlike previous results showing
that parallel-perspective stereo has a constant depth error, we
conclude that the depth estimation error of stereo mosaics is in fact a
linear function of the absolute depths of a scene. Experimental results
on long video sequences are given.</span></font></div>
