Abstract:
This paper describes an unbounded resolution paint system. The image is represented
using a bi-orthogonal wavelet basis. The wavelet framework makes it possible
to implement the necessary multiscale image operations in an efficient manner and
without artifacts. This approach has also many other advantages, including conciseness
of the representation.
The architecture of the unbounded resolution paint system is presented and a full
2D implementation is provided.
