Principal curvatures from the integral invariant viewpoint
The extraction of curvature information for surfaces is a basic problem of Geometry Processing. Recently an integral invariant solution of this problem was presented, which is bas...

Haptic Perception of Real and Virtual Curvature
Abstract. In this study we compared human discrimination performance for real and virtual curved shapes. To simulate a curved shape we used a device that could independently orient...

3D face detection using curvature analysis
Face detection is a crucial preliminary in many applications. Most all the approaches to face detection have focused on the use of two-dimensional images. We present an innovative...

Surface Stereo with Soft Segmentation
This paper proposes a new stereo model which encodes the simple assumption that the scene is composed of a few, smooth surfaces. A key feature of our model is the surfacebased rep...
