Structure and Motion from Silhouettes
This paper addresses the problem of recovering structure and motion from silhouettes. Silhouettes are projections of contour generators which are viewpoint dependent, and hence do...

Affine 3-D Reconstruction from Two Projective Images of Independently Translating Planes
Consider two views of a multi-body scene consisting of planar bodies moving in pure translation one relative to the other. We show that the fundamental matrices, one per body, liv...

On Projection Matrices and their Applications in Computer Vision
Projection matrices from projective spaces ? to ? have long been used in multiple-view geometry to model the perspective projection created by the pin-hole camera. In this work we...

Camera Calibration and 3D Reconstruction from Single Images Using Parallelepipeds
In this paper, parallelepipeds and their use in camera calibration and 3D reconstruction processes are studied. Parallelepipeds naturally characterize rigidity constraints present...

Deriving Intrinsic Images from Image Sequences
Intrinsic images are a useful midlevel description of scenes proposed by Barrow and Tenenbaum [1]. An image is decomposed into two images: a reflectance image and an illumination ...

Shape Deformation: SVM Regression and Application to Medical Image Segmentation
This paper presents a novel landmark-based shape deformation method. This method effectively solves two problems inherent in landmark-based shape deformation: (a) identification o...

Image Segmentation with Minimum Mean Cut
We introduce a new graph-theoretic approach to image segmentation based on minimizing a novel class of `mean cut' cost functions. Minimizing these cost functions corresponds ...

Error Analysis of Pure Rotation-Based Self-Calibration
Self-calibration using pure rotation is a well-known technique and has been shown to be a reliable means for recovering intrinsic camera parameters. However, in practice, it is vir...

Optimal Motion Estimation from Multiview Normalized Epipolar Constraint
In this paper, we study the structure from motion problem as a constrained nonlinear least squares problem which minimizes the so called reprojection error subject to all constrai...
