Visual Computing

This paper addresses the problem of remapping the disparity range of stereoscopic images and video.

We present a novel, integrated system for content-aware video retargeting.

We propose a semi-analytic solution to the problem where the spherical silhouette of the visibility is computed using a search over a 4D dual mesh of the scene. Once computed, we are able to semi-analytically integrate visibility-masked spherical functions along the visibility silhouette, instead of over the entire hemisphere.

We present an efficient many-light algorithm for simulating indirect illumination in, and from, participating media. Instead of creating discrete virtual point lights (VPLs) at vertices of random-walk paths, we present a continuous generalization that places virtual ray lights (VRLs) along each path segment in the medium.

Marker-less motion capture is a challenging problem, particularly when monocular video is all that is available. We estimate biped control from monocular video by implicitly recovering physically plausible three-dimensional motion of a subject along with a character model (controller) capable of replaying this motion in other environments and under physical perturbations.

We present a technique for learning clothing models that enables the simultaneous animation of thousands of detailed garments in real-time.

In this paper, we present a new real-time algorithm for computing volumetric shadows in single-scattering media on the GPU.

In our work, we experiment with motion depiction as a first-class entity within the rendering process.

This paper introduces a new error metric for irradiance caching that significantly outperforms the classic Split-Sphere heuristic.
