Trajectory Basis for Nonrigid Structure from Motion – Project Page

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…

ICCV 2011 – Multiview Structure from Motion in Trajectory Space

Aamer Zaheer, Ijaz Akhter, Mohammad Haris Baig, Shabbir Marzban, Sohaib Khan International Conference on Computer Vision, ICCV, 2011 Abstract Most nonrigid objects exhibit temporal regularities in their deformations. Recently it was proposed that these regularities can be parameterized by assuming that the non- rigid structure lies in a small dimensional trajectory space. In this paper,…
