ABSTRACT
The paper computes the reliability of estimates of image
motion parameters. The use of such measures of reliability
to weight motion estimates improves significantly the per-
formance of motion analysis tasks such as the recovery of
3D structure [1, 2]. The paper relates both the estimation
error variance and the stability of the estimation algorithm
with the spatial gradient of the image brightness pattern. We
illustrate the predictions of our expressions with several im-
age brightness patterns.
