我们提出了一种新的技术,产生二维低差异(LD)的蓝噪声点集采样。使用一维二进制货车derCorput序列,我们构建二维LD点集,并重新排列它们以匹配目标光谱轮廓,同时保持它们的低差异。我们将重排信息存储在一个紧凑的查找表中,该查找表可用于生成任意大的点集。我们评估我们的技术,并将其与最先进的采样方法进行比较。
We present a novel technique that produces two-dimensional low-discrepancy (LD) blue noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we construct two-dimensional LD point sets, and rearrange them to match a target spectral profile while preserving their low discrepancy. We store the rearrangement information in a compact lookup table that can be used to produce arbitrarily large point sets. We evaluate our technique and compare it to the state-of-the-art sampling approaches.
