THE APPLICATIONS OF UNCALIBRATED OCCLUSION JUNCTIONS

A. Broadhurst and R. Cipolla

Sept 1999

When a scene is viewed from two different viewpoints there are often regions which are only visible in one of the two views. These occluded regions give important information about depth discontinuities in the image. When a background line is obscured by a foreground object, it forms a T-junction in the image, and these junction points can be used to detect occlusion.

Two algorithms are presented in this paper. The first algorithm uses the trifocal tensor to automatically locate T-junctions visible in three views, whilst the second application uses junction points to obtain a constraint for the detection of planar surfaces.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
