Volume data expression and visualization based on multi-scale tensor approximation
Qin Hongxin · Computer Engineering and Applications Journal · 2011
Real time volume visualization is supported by modern graphics hardware currently.However,with the development of scanning technology,the performance in GPU memory is still a bottleneck for large volume data visualization.Thus it is very important to find a compression method which can preserve volume feature.It is developed based on tensor approximation.The approach can be used for data compression based on multi-scale tensor approximation.At the same time,volume feature is preserved since compression base is extracted from data.The obtained results show that the approach is valid.
