Ijaz Akhter, Yaser Sheikh, Sohaib Khan, Takeo Kanade Abstract Existing approaches to nonrigid structure from motion assume that the instantaneous 3D shape of a deforming object is a linear combination of basis shapes. These basis are object dependent and therefore have to be estimated anew for each video sequence. In contrast, we propose a dual approach to describe the evolving […]

Ijaz Akhter, Yaser Sheikh, Sohaib Khan IEEE Conference on Computer Vision and Pattern Recognition (CVPR) 2009 (Oral, 4.1% acceptance rate) Abstract In factorization approaches to nonrigid structure from motion, the 3D shape of a deforming object is usually modeled as a linear combination of a small number of basis shapes. The original approach to simultaneously […]
