Abstract
A general method of calculating the precision of environmental
parameters which differs from conventional methods by finding analytical
results, and which does so using only information in the image is
discussed. This method called uncertainty-analysis, is applied to the
case of first-order-error-based motion algorithms for determining
environmental depth by matching corresponding points between two or more
frames of a dynamic image sequence. How to calculate the uncertainty of
in predicted values for the depth is shown, as well as how to calculate
the search region for further instances of the point in subsequent
frames, based only on information present in the image. The analysis is
applied to a real image sequence with good results
