We revisit stereo matching functions, a topic that is considered
well understood, from a different angle. Our goal
is to discover a transformation that operates on the cost
or similarity measures between pixels in binocular stereo.
This transformation should produce a new matching curve
that results in higher matching accuracy. The desired transformation
must have no additional parameters over those
of the original matching function and must result in a new
matching function that can be used by existing local, global
and semi-local stereo algorithms without having to modify
the algorithms. We propose a transformation that meets
these requirements, taking advantage of information derived
from matching the input images against themselves.
We analyze the behavior of this transformation, which we
call Self-Aware Matching Measure (SAMM), on a diverse
set of experiments on data with ground truth. Our results
show that the SAMM improves the performance of dense
and semi-dense...
