Fundamental Matrix for Cameras with Radial Distortion
When deploying a heterogeneous camera network or when we use cheap zoom cameras like in cell-phones, it is not practical, if not impossible to off-line calibrate the radial distor...

Implementing a natural user interface for camera phones using visual tags
Pointing is a natural way of communicating. Children in all cultures use pointing inherently. Attaching tags to our environment enables interaction by pointing. Visual tags are a g...

3-D Shape Reconstruction from Camera Motion with Inexact Motion Parameters
When a sequence of images are obtained by a moving camera, if the exact camera velocity and corresponding points on the images are determined, the 3-D shape of the object can be r...

Continuous Time Matching Constraints for Image Streams
Corresponding image points of a rigid object in a discrete sequence of images fulfil the so-called multilinear constraint. In this paper the continuous time analogue of this const...

An Efficient Solution to the Five-Point Relative Pose Problem
An efficient algorithmic solution to the classical five-point relative pose problem is presented. The problem is to find the possible solutions for relative camera motion between ...
