Subpixel Registration in Renal Perfusion MR Image Sequence
We propose a subpixel registration algorithm to deal with the motion induced by breathing for renal perfusion MR image sequences. Our approach minimizes an energy functional that ...

Looking at the surprise: Bottom-up attentional control of an active camera system
—Inspired by the expectation-based perception of humans, a surprise-driven active vision system is proposed. This vision system not only considers spatial saliency of objects in ...

Unsupervised dynamic texture segmentation using local spatiotemporal descriptors
Dynamic texture (DT) is an extension of texture to the temporal domain. In this paper, we address the problem of segmenting DT into disjoint regions in an unsupervised way. Each r...
