Attention to 3-D shape, 3-D motion, and texture in 3-D structure from motion displays.
We used fMRI to directly compare the neural substrates of three-dimensional (3-D) shape and motion processing for realistic textured objects rotating in depth. Subjects made judgments about several different attributes of these objects, including 3-D shape, the 3-D motion, and the scale of surface texture. For all of these tasks, we equated visual input, motor output, and task difficulty, and w...
متن کامل3-D Structure from Visual Motion: Modeling, Representation and Observability
The problem of \Structure From Motion" concerns the reconstruction of the three-dimensional structure of a scene from its projection onto a moving two-dimensional surface. Such a problem is solved eeectively by the human visual system, judging from the ease with which we perform delicate control tasks involving vision as a sensor such as reaching for objects in the environment or driving a car....

SIMULATION OF 3D MODEL, SHAPE, AND APPEARANCE AGING BY PHYSICAL, CHEMICAL, BIOLOGICAL, ENVIRONMENTAL, AND WEATHERING EFFECTS Joseph T. Kider Jr. Supervisor : Norman I. Badler Physical, chemical, biological, environmental, and weathering effects produce a range of 3D model, shape, and appearance changes. Time introduces an assortment of aging, weathering, and decay processes such as dust, mold, ...
متن کاملSufficient Image Structure for 3-D Motion and Shape Estimation
We derive suucient conditions on image structure that permits determination of 3-D motion parameters and depth from motion relative a rigid surface in front of the camera. We assume that only the rst order spatio-temporal derivative or of the image is given and that the image intensity is continuously diierentiable everywhere or that image contours are continuously diierentiable. This means tha...
متن کاملVisual perception of motion and 3-D structure from motion: an fMRI study.
Functional magnetic resonance imaging was used to study the cortical bases of 3-D structure perception from visual motion in human. Nine subjects underwent three experiments designed to locate the areas involved in (i) motion processing (random motion versus static dots), (ii) coherent motion processing (expansion/ contraction versus random motion) and (iii) 3-D shape from motion reconstruction...
