Abstract :
Beamlets are combined with zero-tree coding algorithm to create a new coding method, particularly suitable for lines and curves. Beamlets are a multiscale collection of line segments at a range of scales, location, having a variety of lengths and orientations. The new coding scheme - named JBEAM is more efficient - in terms of bit rates - in coding binary curvy images in simulations.
