We apply the Estimation-Quantization (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 in a rate-distortion optimal fashion, we improve upon the recently proposed zerotree normal mesh compression algorithm by 0.5 to 1 dB in distortion.engEstimation-QuantizationNormal Meshes3D Geometry codingImage Processing and Pattern analysisWavelet based Signal/Image ProcessingMultiscale MethodsSignal Processing ApplicationsMultiscale geometry processingConference paperEstimation-QuantizationNormal Meshes3D Geometry coding
