Abstract
The estimation of Global or Camera motion from image sequences is important both for video
retrieval and compression (MPEG4). This is frequently performed using robust M-estimators with
the widely used Iterative Reweighted Least Squares algorithm. This article presents an investigation
of the use of an alternative robust estimation algorithm and illustrates its improved computationnal
efficiency. The paper also introduces two new confidence measures which can be used to validate
camera motion measurements in the context of information retrieval.
