Multiresolution Signal Processing for Meshes


Igor Guskov       Wim Sweldens       Peter Schröder


Abstract: We generalize basic signal processing tools such as downsampling, upsampling, and filters to irregular connectivity 3D triangular meshes. This is accomplished through the design of a non-uniform relaxation procedure whose weights depend on the geometry and we show its superiority over existing schemes whose weights only depend on connectivity. This is combined with known mesh simplification methods to build subdivision, pyramid, and wavelet algorithms. We demonstrate the power of these algorithms through a number of application examples including smoothing, enhancement, editing, and texture mapping.
