This paper presents a biologically-inspired approach for human tracking by using a single feature of opponent-motion and visual attention mechanism. Opponent-motion is a significant and salient feature during human motion of walking, running, etc. By the interaction with the heuristic prior knowledge of human model, the obtained opponent-motion is used to derive motion saliency from its statistical...
We report patient motion in 110 Tl-201 cardiac perfusion SPECT studies in 66 patients. The imaging consisted of emission followed by sequential transmission imaging during which motion tracking with a visual tracking system (VTS) was performed. We investigated the extent, time, and frequency of respiratory and rigid-body motion in these patients. We also determined whether the motion occurred gradually...
