> Abstract
> We address the problem of representing captured images in
> the continuous mathematical space more usually associated
> with certain forms of drawn (‘vector’) images. Such an image
> is resolution-independent so can be used as a master for
> varying resolution-specific format
> s. We briefly describe the
> main features of a vectorisi
> ng codec for photographic images,
> whose significance is that drawing programs can access
> images and image components as
> first-class vector objects.
> This paper focuses on the problem of rendering from the
> isochromic contour form
> of a vectorised image and
> demonstrates a new fill algorithm which could also be used in
> drawing generally. The fill method is described in terms of
> level set diffusion equations for
> clarity. Finally we show that
> image warping is both simplified and enhanced in this form
> and that we can demonstrate real histogram equalisation with
> genuinely rectangular histograms.
