Abstract
Many of the todays visual servoing systems rely on use of markers on the object to provide features for control. There is thus a need for a visual system that provides control features regardless of the appearance of the object. Region based tracking is a natural approach since it does not require any special type of features. In this paper we present two different approaches to region based tracking: a) a multi-resolution gradaent based approach (using optical Bow) and b) a discrete feature based search approach. We present experiments conducted with both techniques for dafferent types of image motions. Finally, the performance, drawbacks and limitations of used techniques are discussed. 1
