Multiresolution triangulation meshes are widely used in computer graphics for representing three-dime (3-d) shapes. We propose to use these tools to represent 2-d piecewise smooth functions such as graysca because triangles have potential to more efficiently approximate the discontinuities between the smooth pi other standard tools like wavelets. We show that normal mesh subdivision is an efficient triangulation, thanks t its localadaptivityto the discontinuities. Indeed, we prove that, within… CONTINUE READING
