3-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....
متن کاملAdvanced Motion Modeling for 3 D Video Coding
Driven by new multimedia applications and the growing demand for more flexible and efficient transmission of video, a new approach to video coding has been recently proposed as an alternative to classical hybrid schemes. Instead of sequential frame-based predictive processing, the new approach is based on spatio-temporal 3D transforms, open-loop nonpredictive processing, and embedded quantizati...
متن کامل3-D Motion Estimation
II. 3-D Motion Estimation The approach for 3-D motion estimation in this project has two stages: 3-D shape reconstruction and model-based 3-D motion estimation. The object shape in a video sequence is usually unknown. A structure from motion algorithm is first applied to reconstruct an approximate 3D shape from several views of the video sequence. With the approximate object shape, a model-base...
متن کاملAttention 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 کاملMotion Contrast 3 D Scanning
We present a new method for structured light 3D scanning called Motion Contrast 3D scanning (MC3D). The key principle behind MC3D is the conversion of spatial projector-camera disparity to temporal events recorded by a motion contrast sensor [1]. The idea of mapping disparity to time has been explored previously in the VLSI community, where several researchers have developed highly customized C...
