Abstract
The process of grouping and subsequently recog­
nising objects in cluttered images is one laden with
di#culties; however, results can be greatly enhanced
if the inherent uncertainty of image­features is taken
into account. This paper shows that starting with the
individual edgel's uncertainty it is possible to calcu­
late covariance­information for all derived quantities.
This information can be used to choose between com­
peting algorithms, selecting the one that produces the
more reliable results, but also as an aid during the
recognition process. The consequent application of
error­propagation leads to a new formulation for the
