Change in the system's dynamic properties, conditioned by the correlation of the multiplicative per- turbations, appears in the model of (2.1) and (2.2) as a change in the deterministic matrix of object  ...  In the struc- ture of these equations there are reflected the effects, well known from practice, of detection and changes of dynam- ic properties of systems.  ... 

The situated laptop: A tangible interface for computer-based studies of surface appearance

B. Darling, J. Ferwerda
2010 Journal of Vision  
The user experience is akin to holding a physical surface in one's hands and being able to actively tilt it and observe it from different directions to see the changing patterns and properties of environmental  ...  Under real-world conditions, to understand surface properties, observers often engage in complex behaviors that involve active manipulation and dynamic viewpoint changes.  ...  and dynamic viewpoint changes that may be used to help assess the surface properties of a real object.  ...

Object Tracking Using Globally Coordinated Nonlinear Manifolds

Che-Bin Liu, Ruei-Sung Lin, Ming-Hsuan Yang, N. Ahuja, S. Levinson
2006 18th International Conference on Pattern Recognition (ICPR'06)  
In this paper, we parameterize the mixture of linear appearance subspaces of an object in a global coordinate system, and apply it to visual tracking using a Rao-Blackwellized particle filter.  ...  We present a dynamic inference algorithm in a globally parameterized nonlinear manifold and demonstrate it on the problem of visual tracking.  ...  The current pose estimation becomes a strong prior while tracking the next frame and prevents our tracker from being distracted by other objects with similar appearances.  ...

Tangible display systems: direct interfaces for computer-based studies of surface appearance

Benjamin A. Darling, James A. Ferwerda, Bernice E. Rogowitz, Thrasyvoulos N. Pappas
2010 Human Vision and Electronic Imaging XV  
When evaluating the surface appearance of real objects, observers engage in complex behaviors involving active manipulation and dynamic viewpoint changes that allow them to observe the changing patterns  ...  This information was integrated with a 3D rendering module so that rotating the display or moving in front of the screen would produce realistic changes in the appearance of virtual objects.  ...  Unlike a real object, the use of a tangible display system provides the capability to change the properties of the material dynamically.  ...

Dynamic Scene Segmentation through Object Hypotheses Ranking

Yinhui Zhang, Zifen He, Xing Wu
2015 International Journal of Signal Processing, Image Processing and Pattern Recognition  
Inside object candidates derived from spatial features in each frame are first estimated.  ...  We demonstrate the performance of our approach through experimental evaluation on a typical dynamic scene benchmark from Freiburg-Berkeley Motion Segmentation Dataset.  ...  Actually, bottom-up segmentation based on appearance cues always leads to oversegmentation of dynamic scenes and cannot segment foreground objects from background scenes.  ...

Effect of contextual information on object tracking

Mohammad Hedayati, Michael J. Cree, Jonathan B. Scott
2017 2017 International Conference on Image and Vision Computing New Zealand (IVCNZ)  
Local object information, such as the appearance and motion features of the object, are useful for object tracking in videos provided the object is not occluded by other elements in the scene.  ...  During occlusion, however, the local object information in the video frame does not properly represent the true properties of the object, which leads to tracking failure.  ...  Consequently, the location of the object can be estimated by tracking the points that sample from the same objects.  ...
