Shape Clustering and Spatial-temporal Constraint for Non-rigid Structure from Motion
Non-rigid Structure-from-Motion (NRSfM) is an active research eld in computer vision. The task of NRSfM is to simultaneously recover camera motion and 3D structure from 2D tracks of a deformable object. This problem is generally categorized into sparse and dense cases in terms of scale, where sparse NRSfM deals with a few feature tracks and dense NRSfM recovers the 3D position of each pixel in an image ow. As NRSfM is essentially an under-constrained problem, recent research has...[Show more]
