SpringLens Distributed Nonlinear Magnifications

We present a flexible, distributed and effective technique to model custom d istortions of images. The main idea is to use a mass-spring model to create a flexible surface and to create distor tions by changing the rest-lengths. A physical simulation works out the displacements of this particle grid. We pro vide intuitive tools to interactively design such nonlinear magnifications. In addition, our system enables da ta-driven distortions which allows us to use it for automatic nonlinear magnifications. We demonstrate this with an applic tion for labeling of 3D scenes.
