This paper presents a novel algorithm for calibrating multiple casually placed projectors, via a single uncalibrated camera, to produce a "wallpaper" projection, which is equivalent to printing a single image onto a flat sheet of paper and pasting it to the screen. Based on a piecewise planar model, the method described here combines the advantages of(More)

This report addresses the problem of calibrating camera parameters such as lens distortion and color scaling using variational methods. We have presented multi-view stereo techniques based on variational ideas to (i) evolve pose parameters of a 3D model object to take advantage of the known shape of calibration objects, and to reduce computational(More)
A variety of techniques have been proposed to manipulate objects in three dimensions using only a two-dimensional input device, such as a standard mouse. Some of these methods lacked full six degree of freedom (DOF) control, instead manipulating only the two DOF orientation of the object. Others provide six DOF control at the cost of complex user operations(More)
