in this paper we emphasize the importance of questioning the global validity of significant concepts underpinning global health policy. this implies questioning the concept of global health as such and accepting that there is no global definition of the global. further, we draw attention to ‘quality’ and ‘empowerment’ as examples of world-forming concepts. these concepts are exemplary for the g...

This paper presents a new method for estimating piecewise-smooth optical flow. We propose a global optimization formulation with three-frame matching and local variation and develop an efficient technique to minimize the resultant global energy. This technique takes advantage of local gradient, global gradient and global matching methods and alleviates their limitations. Experiments on various ...
