SBL Mesh Filter: Fast Separable Approximation of Bilateral Mesh Filtering Additionnal Materials

Figure 2: Our approximation scheme provides similar results when compared to exact bilateral filtering while being several times faster. From top left to bottom right : a noisy mesh, bilateral filtering, Laplacian filtering, separable bilateral (SBL) filtering decomposed along unsmoothed curvature direction (SBL-u), SBL using random directions (SBL-r) and SBL using smoothed curvature directions (SBL-s). The error maps are given on a per-vertex basis using L norm. Figure 3: Filtering error. Histograms of the per-vertex error between the filtered meshes and the original one. It is very difficult to detect the difference between the two curves, wich demonstrates the good approximation of our method.
