Stereo-Based Obstacle Avoidance in Indoor Environments with Active Sensor Re-Calibration
We present a stereo-based obstacle avoidance system for mobile vehicles. The system operates in three steps. First, it models the surface geometry of supporting surface and remove...

Estimation of Surface Normal of a Curved Surface Using Texture
Shape-from-Texture is the problem of estimating an object’s shape by examining the apparent distortions in the surface texture of the object due to image capture. A new method is...

Optimization-Based Virtual Surface Contact Manipulation at Force Control Rates
Previous interactive works have used springs, heuristics, and dynamics for surface placement applications. We present an analytical technique for kilohertz rate manipulation of CA...

Stellar Subdivision Grammars
In this paper we develop a new description for subdivision surfaces based on a graph grammar formalism. Subdivision schemes are specified by a context sensitive grammar in which ...
