Sequential Bayesian Non-Rigid Structure from Motion
This thesis1 addresses the problem of recovering simultaneously camera motion and the 3D reconstruction of deformable objects from monocular video. We propose several methods to solve this problem in a sequential fashion, frame-by-frame estimation, as the data arrives. Deformable structures appear constantly in our everyday life, from human non-rigid motion (e.g., a smiling face or performing d...
متن کاملDiscriminating rigid from nonrigid motion: minimum points and views.
Theoretical investigations of structure from motion have demonstrated that an ideal observer can discriminate rigid from nonrigid motion from two views of as few as four points. We report three experiments that demonstrate similar abilities in human observers: In one experiment, 4 of 6 subjects made this discrimination from two views of four points; the remaining subjects required five points. ...
متن کامل3D Structure from 2D Motion
In their day-to-day lives, people naturally understand and operate in a three dimensional world. Curiously, though, they only sense 2D projections of it. The seemingly e ortless act of inferring 3D from 2D observations is the result of complex mechanisms that are still quite far from being resolved. For many years, this task has been considered the primary role of visual processing. Pioneers in...
متن کاملNon-Rigid Structure from Motion for Complex Motion
Recovering deformable 3D motion from temporal 2D point tracks in a monocular video is an open problem with many everyday applications throughout science and industry, or the new augmented reality. Recently, several techniques have been proposed to deal the problem called Non-Rigid Structure from Motion (NRSfM), however, they can exhibit poor reconstruction performance on complex motion. In this...
متن کامل2D Motion Estimation in the Extraction of 3D Motion and Structure of Rigid Objects
Two-dimensional motion estimation is a task that emerges in several elds of research such as coding and compression, content-based video retrieval and computer vision. The problem has been tackled by several authors and various algorithms can be found in the literature focusing either on accuracy or low computational cost. Present work investigates the e cient application of existing motion est...
