A new quantization method for 3-D seismic visualization

摘要

The seismic data is a kind of high dynamic range data, which is very difficult to realize high-quality visualization. In this paper, we present a new method to scale the high-dynamic-range seismic data for visualization, which can quantize the high-dynamic-range data into the low-dynamic-range data, while preserving the high frequency characteristics of the geological structure. We divide the seismic data into two parts, the large-scale geological structure part and the small-scale geological structure part. The large-scale part is obtained using an edge-preserving filter called bilateral filter. Then the small-scale part and the processed large-scale part are merged into a new seismic data. Finally, the new generated data is scaled by the histogram-based quantization algorithm to a low-dynamic-range data. In this paper, we discuss and implement our quantization algorithm, and give the results.
