Existing computational models of structurefrom-motion-the appearance of three-dimensional motion generated by moving two-dimensional patterns-are all based on variations of Optical flow or feature point correspondence within the interior of single objects. Three separate phenomena provide strong evi

β¦ Synopsis
Active visual tracking of points on occlusion boundaries can simplify certain computations involved in determining scene structure and dynamics based on visual motion. Tracking is particularly effective at surface boundaries where large, discontinuous changes in depth are occurring. Two such techniques are described here. The first provides a measure of ordinal depth by distinguishing between occluding and occluded surfaces at a surface boundary. The second can be used to determine the direction of observer motion through a scene.

In this paper, we propose a novel dimensionality reduction method, temporal neighbor preserving embedding (TNPE), to learn the low-dimensional intrinsic motion manifold of articulated objects. The method simultaneously learns the embedding manifold and the mapping from an image feature space to an e
## Abstract In methods for extracting threeβdimensional structure by conventional spatiotemporal image analysis, camera motion was restricted to constant velocity linear motion in order to use epipolar constraints. In this paper, we are proposing a method for extracting threeβdimensional structure
## Abstract We propose a method for tracking a moving object in a specified direction from time sequence images which include multiple moving objects, assuming that a camera rotates to look at the specified object. First, an image analytic signal is generated by spatialβHilbert transform. The horiz
