Evaluating Image Quality Measures to Assess the Impact of Lossy Data Compression Applied to Climate Simulation Data
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Applying lossy data compression to climate model output is an attractive means of reducing the enormous volumes of data generated by climate models. However, because lossy data compression does not exactly preserve the ... -
Evaluation of the compressibility of Computer-Generated Holograms
(The Eurographics Association, 2015)We present a preliminary investigation of the compressibility of Physically-Based Computer-Generated Holograms (PB CGHs) as represented in various bases. The goal is to identify which bases, if any, are suitable for applying ... -
Perceptually Motivated Real-Time Compression of Motion Data Enhanced by Incremental Encoding and Parameter Tuning
(The Eurographics Association, 2013)We address the problem of efficient real-time motion data compression considering human perception. Using incremental encoding plus a database of motion primitives for each key point, our method achieves a higher or ... -
Stochastic Depth Buffer Compression using Generalized Plane Encoding
(The Eurographics Association and Blackwell Publishing Ltd., 2013)In this paper, we derive compact representations of the depth function for a triangle undergoing motion or defocus blur. Unlike a static primitive, where the depth function is planar, the depth function is a rational ... -
Towards Efficient Online Compression of Incrementally Acquired Point Clouds
(The Eurographics Association, 2014)We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ... -
Variable Length Coding for GPU-Based Direct Volume Rendering
(The Eurographics Association, 2016)The sheer size of volume data sampled in a regular grid requires efficient lossless and lossy compression algorithms that allow for on-the-fly decompression during rendering. While all hardware assisted approaches are based ...
