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...

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...

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 ...

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 ...

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...

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...
