generally obtained by using the luminance-chrominance Luv space, which seems to
be a suitable color space for stereo matching.

In sum, in this chapter has described a preliminary investigation into the utility of
color information in solving the stereo correspondence problem. The results of this
investigation strongly indicate that using color information can significantly im-
prove the precision of color stereo matching, especially when a suitable color sys-
tem is chosen. We found that the luminance-chrominance Luv color space offers the
best performances. We also shown that the RGB space, which is the most popular
color model in stereo matching, only achieves average results.
