Abstract

In this article, we consider the robust estimation of a location parameter using M-estimators. We propose coupling this estimation with the robust scale estimate introduced in [Dahyot and Wilson, 2006]. The resulting procedure is completely unsupervised. It is applied to camera motion estimation and moving object detection in videos. Experimental results on different video materials demonstrate the adaptability and the accuracy of this new robust approach.
