Normal Mesh Compression

چکیده
Normal meshes were recently introduced as a new way to represent geometry. A normal mesh is a multiresolution representation which has the property that all details lie in a known normal direction and hence the mesh depends only on a single scalar per vertex. Such meshes are ideally suited for progressive compression. We demonstrate such a compression algorithm for normal meshes representing complex, arbitrary topology surfaces as they appear in 3D scanning and scientific visualization. The resulting coder is shown to exhibit gains of an additional 2-5dB over the previous state of the art.

Semi-Regular 3D Mesh Progressive Compression and Transmission based on an Adaptive Wavelet Decomposition
We introduce a new patch-based multi-resolution analysis of semi-regular mesh surfaces. This analysis brings patch-specific wavelet decomposition, quantization and encoding to the mesh compression process. Our underlying mesh partitioning relies on surface roughness (based on frequency magnitude variations), in order to produce patches, representative of semantic attributes of the object. With ...

متن کاملEstimation-Quantization Geometry Coding Using Normal Meshes
We propose a new algorithm for compressing three-dimensional triangular mesh data used for representing surfaces. We apply the EstimationQuantization (EQ) algorithm originally designed for still image compression to the normal mesh wavelet coefficients. The EQ algorithm models the wavelet coefficients as a Gaussian random field with slowly varying standard deviation. By designing the quantizers...
متن کاملAdapted Semi-Regular 3-D Mesh Coding Based on a Wavelet Segmentation
We present a local wavelet decomposition framework based on a segmentation of semi-regular meshes and mostly dedicated to mesh compression purposes. The shape partition has been created to adapt the compression in the regions where the wavelet coefficients have a non negligible magnitude or polar angle (the angle with the normal vector), reflecting the high frequencies of the model. This partit...
متن کاملA Framework for Data-driven Progressive Mesh Compression
Progressive mesh compression techniques have reached very high compression ratios. However, these techniques usually do not take into account associated properties of meshes such as colors or normals, no matter their size, nor do they try to improve the quality of the intermediate decompression meshes. In this work, we propose a framework that uses the associated properties of the mesh to drive...
