Invariant representations in object recognition systems are generally obtained by pooling feature vectors over spatially local neighborhoods. But pooling is not local in the featu...

Abstract. We propose a novel method for action detection based on a new action descriptor called a shape flow that represents both the shape and movement of an object in a holistic...

Four statistical visual feature indexes are proposed: SLM (Shot Length Mean), the average length of each shot in a video; SLD (Shot Length Deviation), the standard deviation of sh...

We present an approach that directly uses curvature cues
in a discriminative way to perform object recognition. We
show that integrating curvature information substantially
