This proposal aims to revisit one of the most fundamental issues in graphics, namely the representation of images. The idea is to re-cast sampled images into a continuous representation which is as close as possible to the original form from which the samples were taken. The research questions we are asking are 1, whether the continuous-space approximations we can derive from the samples are close enough to the original so that re-sampling results in a visually indistinguishable image and 2, whether we can exploit the continuous-space representation in ways not open to the sampled form. The hypothesis we wish to establish is that continuous-space formats for close photogrammetry data would allow considerably more accurate 3D recovery than the corresponding process using sampled representations throughout.We will be using digitised film sequences for our data with a view to taking advantage of the same entities being presented with various samplings and orientations in successive images. We will use arc-length approximating non-uniform B-splines for contours and the use of contour data to reconstruct segment borders to subpixel accuracy for blue-screen (compositing) and other purposes.
