Abstract
This paper sets out a new representation of an image which is contra;st ind ependent. The image is decomposed into a tree of "shapes" based on connecte d components of level sets, which provides a full and nonredundant represen tation of the image. A fast algorithm to compute the tree, the fast level l ines transform (FLLT), is explained in details. Some simple and direct appl ications of this representation are shown.
