These include label sequences for traditional IE, segmentation models for entity-level extractions, and skip chain models for collective labeling. I will present efficient inference algorithms for finding the highest scoring (MAP) prediction for two interesting types of structured models in IE. I will then present our recent results in max-margin training of such models. There are two popular formulations for maximum margin training of structured spaces: margin scaling and slack scaling. While margin scaling is extremely popular since it requires the same kind of MAP inference as prediction, slack scaling is believed to be more accurate and better-behaved. I will describe an efficient variational approximation to the slack scaling method that solves its inference bottleneck while retaining its accuracy advantage over margin scaling. Further I argue that existing scaling approaches do not separate the true labeling comprehensively while generating violating constraints. I will propose a new max-margin trainer PosLearn that generates violators to ensure separation at each position of a decomposable loss function.

In a single snapshot, they enable digital image refocusing, ie, the ability to change the camera focus after taking the snapshot, and 3D reconstruction. We show that they also achieve a larger depth of field while maintaining the ability to reconstruct detail at high resolution. More interestingly, we show that their depth of field is essentially inverted compared to regular cameras. Crucial to the success of the light field camera is the way it samples the light field, trading off spatial vs. angular resolution, and how aliasing affects the light field. We present a novel algorithm that estimates a full resolution sharp image and a full resolution depth map from a single input light field image. The algorithm is formulated in a variational framework and it is based on novel image priors designed for light field images. We demonstrate the algorithm on synthetic and real images captured with our own light field camera, and show that it can outperform other computational camera systems.

We present a novel, scalable approach for simulating such crowds, using a dual representation both as discrete agents and as a single continuous system.

This approach makes it possible to simulate very large, dense crowds composed of up to a hundred thousand agents at near interactive rates on desktop computers [Rahul Narain, Abhinav Golas, Sean Curtis, and Ming C.

Existing interactive mesh composition tools focus on atomic copy-and-paste of pre-selected feature areas, and are either limited to copying surface displacements, or require the solution of variational optimization problems, which is too expensive for an interactive brush interface. In contrast, our GeoBrush method supports real-time continuous copying of arbitrary high-resolution surface features between irregular meshes, including topological handles. We achieve this by first establishing a correspondence between the source and target geometries using a novel generalized discrete exponential map parameterization. Next we roughly align the source geometry with the target shape using Green Coordinates with automatically-constructed cages. Finally, we compute an offset membrane to smoothly blend the pasted patch with C^1 continuity before stitching it into the target. The offset membrane is a solution of a bi-harmonic PDE, which is computed on the GPU in real time by exploiting the regular parametric domain. We demonstrate the effectiveness of GeoBrush with various editing scenarios, including detail enrichment and completion of scanned surfaces. www-ui.is.su-tokyo.ac.jp**Mixed Finite Elements for Variational Surface Modeling: Beetle curve**Curve boundary conditions expose tangent control for the biharmonic solution surface.

Abstract: We present a fluid simulation method based on Smoothed Particle Hydrodynamics (SPH) in which incompressibility and boundary conditions are enforced using holonomic kinematic constraints on the density. This formulation enables systematic multiphysics integration in which interactions are modeled via similar constraints between the fluid pseudo-particles and impenetrable surfaces of other bodies. These conditions embody Archimede's principle for solids and thus buoyancy results as a direct consequence. We use a variational time stepping scheme suitable for general constrained multibody systems we call SPOOK. Each step requires the solution of only one Mixed Linear Complementarity Problem (MLCP) with very few inequalities, corresponding to solid boundary conditions. We solve this MLCP with a fast iterative method. Overall stability is vastly improved in comparison to the unconstrained version of SPH, and this allows much larger time steps, and an increase in overall performance by two orders of magnitude. Proof of concept is given for computer graphics applications and interactive simulations.**Changing cylinder, hole and fillet radius in Rhino**RhinoDirect 0.3 video tutorial.
