Stabilized Structure from Motion without Disparity Induces Disparity Adaptation
3D structures can be perceived based on the patterns of 2D motion signals. With orthographic projection of a 3D stimulus onto a 2D plane, the kinetic information can give a vivid impression of depth, but the depth order is intrinsically ambiguous, resulting in bistable or even multistable interpretations. For example, an orthographic projection of dots on the surface of a rotating cylinder is p...
متن کاملMotion Estimation from Disparity Images
A new method for 3D rigid motion estimation from stereo is proposed in this paper. The appealing feature of this method is that it directly uses the disparity images obtained from stereo matching. We assume that the stereo rig has parallel cameras and show, in that case, the geometric and topological properties of the disparity images. Then we introduce a rigid transformation (called d-motion) ...
متن کاملExtracting 3D structure from disparity.
The neural mechanisms of stereoscopic 3D shape perception have only recently been investigated. Here we review the two cortical regions in which these mechanisms have been studied so far in macaques: a small subpart of inferotemporal cortex called TEs, and the caudal intraparietal (CIP) region. Neurons in TEs respond selectively to the orientation and curvature in depth of stereoscopic surfaces...
متن کاملAdaptation to vertical disparity induced-depth: implications for disparity processing
Depth aftereffects produced by prolonged inspection of an object in depth can be mediated by monocular and binocular depth cues. The adapting mechanisms responsible for such effects have not yet been fully determined. Theories of binocular depth aftereffects typically posit a role of an adaptive horizontal disparity sensitive mechanism, implying multiple cue-specific mechanisms for depth aftere...
متن کاملMotion-Disparity Interaction and the Scaling of Stereoscopic Disparity
Contemporary studies of visual perception often view the observer's problem as one of estimation. In other words, the observer seeks to estimate various aspects of the scene, such as the size and shape of the objects in that scene. The information available to inform this estimation is viewed as consisting of one or more visual cues. Each cue may be used on its own to estimate some aspects of s...
