(Abstract taken from html version)
A new technique has been developed for estimating the projective (homographic) coordinate transformation between pairs of images of a static scene, taken with a camera that is free to pan, tilt, rotate about its optical axis, and zoom. The technique solves the problem for two cases:
The new algorithm is applied to the task of constructing high resolution still images from video. This approach generalizes inter-frame camera motion estimation methods which have previously used an affine model and/or which have relied upon finding points of correspondence between the image frames.
The new method, which allows an image to be created by ``painting with video'' is used in conjunction with a wearable wireless webcam, so that image mosaics can be generated simply by looking around, in a sense, ``painting with looks''.
