Flows, mappings and shapes


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

Workshop Theme

Computer vision and computer graphics have seen significant recent advances in the analysis of 3D shape through the tools of optimization and flows in shape space. Similarly, long standing problems such as image registration and optical flow are increasingly influencing and benefitting from the computational implementations and representations of diffeomorphic and other mappings. Nevertheless, there is a clear opportunity to further expand and intermix the influence of these methods throughout computer vision. On the computer vision side, this workshop will bring together practitioners working on the recovery of shape from the real word (shape from silhouette, single-image reconstruction), shape registration, and general image-to-image registration. The optimization methods employed range from large-scale non-convex techniques where high convergence rates are crucial in practice, to methods on shape spaces and manifolds, where second-order methods are a current hot topic. Shape and registration are already linked via the paradigm of flows, and the workshop is an opportunity to explore the unification of these frameworks with other developing methodologies in computer vision. Examples of such interactions include advanced optimization techniques applied to image enhancement and reconstruction; new image evolution paradigms like non-local means and Beltrami flows for image restoration; interactions with probability theory and statistics, powerful applications of Markov random fields, graphical models and stochastic grammars; the explosion of applications of compressive sensing and sparsity to a wide range of imaging problems; dynamical systems theory applied to video analysis and understanding; interactions with global analysis, geometric mechanics and complex geometry bringing new developments in shape analysis. Because of this flourishing of new methods arising from diverse mathematical backgrounds, it has become more and more challenging for a single researcher to embrace the full spectrum of computer vision fields. This makes the INI programme timely and critically important. This workshop will bring together the leading experts in image processing, computer vision and shape analysis to discuss the directions that have the potential to lead to the next big breakthroughs and their implications for other allied disciplines.
