In this paper, we show that salient regions, detected by a biologically motivated attention system, have a considerably higher repeatability than features detected by standard detectors (Harris-Laplacians and DoG features). If a scene contains a salient region, which differs in one of several possible features from the rest of the scene, the repeatability is close to 100%. In settings in which ...

The use of salient regions is an increasingly popular approach to image retrieval. For situations where object retrieval is required and where the foreground and background can be assumed to have different characteristics, it becomes useful to exclude salient regions which are characteristic of the background if they can be identified before matching is undertaken. This paper proposes a techniq...

In this paper, we present a generic and robust representation of video shots content expressed in terms of salient regions of activity. The proposed approach is based on salient points of the image space, thus minimizing the computational effort. Salient points are extracted from each frame. Their trajectories are computed between successive frames and the global motion model is estimated. Movi...
