Influence of Pose on 3-D Shape Classification: Part II
Last year we presented the influence of pose on threedimensional (3-D) shape classification in the context of a repeatability study. Meaning, that the subjects are repeatedly scanned 10 times and they attempt to assume the same pose each time. It was shown that changes due to a slight pose modification had no detrimental effects for shape classification. This paper discuss a second set of exper...
متن کامل3-D head pose recovery for interactive virtual reality avatars
This paper discusses a tracking method allowing real-time recovery of the three-dimensional (3-D) position and orientation of a moving head. The described method uses a wireframe model of the head, a feature-based matching algorithm, and an extended Kalman filter estimator. The resulting motion tracking system works in a realistic environment without makeup on the face, with uncalibrated camera...
متن کامل3-D Articulated Pose Tracking for Untethered Deictic Reference
Arm and body pose are useful cues for deictic reference– users naturally extend their arms to objects of interest in a dialog. We present some recent progress on untethered sensing of articulated arm and body configuration using robust stereo vision techniques. These techniques allow robust, accurate, real-time tracking of 3-D position and orientation. We demonstrate users’ performance with our...
متن کاملObject pose: perceiving 3-d shape as sticks and slabs.
Estimating the pose (three-dimensional orientation) of objects is an important aspect of 3-D shape perception. We studied the ability of observers to match the pose of the principal axes of an object with the pose of a cross consisting of three perpendicular axes. For objects, we used a long and a flat spheroid and eight symmetric objects with aspect ratios of dimensions of approximately 4:2:1....
متن کاملPose Recognition for Tracker Initialization Using 3 D Models
In this thesis it is examined whether the pose of an object can be determined by a system trained with a synthetic 3D model of said object. A number of variations of methods using P-channel representation are examined. Reference images are rendered from the 3D model, features, such as gradient orientation and color information are extracted and encoded into P-channels. The P-channel representat...
