A Multi-View Nonlinear Active Shape Model Using Kernel PCA

S. Romdhani, S. Gong, A. Psarrou
1999 Procedings of the British Machine Vision Conference 1999  
Recovering the shape of any 3D object using multiple 2D views requires establishing correspondence between feature points at different views.  ...  However changes in viewpoint introduce self-occlusions, resulting nonlinear variations in the shape and inconsistent 2D features between views.  ...  It is assumed that a rough position of a face in the image is known. However the pose is unknown and the matching of the models with the target image recovers both the shape of the face and its pose.  ...

Affine structure from line correspondences with uncalibrated affine cameras

Long Quan, T. Kanade
1997 IEEE Transactions on Pattern Analysis and Machine Intelligence  
The algorithm requires a minimum of seven line correspondences over three views. The key idea is the introduction of a one-dimensional projective camera.  ...  This converts 3D a ne reconstruction of line directions" into 2D projective reconstruction of points". In addition, a line-based factorisation method is also proposed to handle redundant views.  ...  Triggs for their help during the development of this work.  ...

C-arm Tracking and Reconstruction Without an External Tracker [chapter]

Ameet Jain, Gabor Fichtinger
2006 Lecture Notes in Computer Science  
After these points are segmented, a high dimensional non-linear optimization computes all unknown parameters for calibration, C-arm pose, correspondence and reconstruction.  ...  Preliminary phantom experiments indicate an average Carm tracking accuracy of 0.9 o and a 3D reconstruction error of 0.8 mm, with an 8 o region of convergence for both the AP and lateral axes.  ...  By enforcing the "consistency" of these feature points across the images, one can potentially solve for all unknown parameters of calibration, pose recovery, matching, and reconstruction in one fell swoop  ...
