5D covariance tracing for efficient defocus and motion blur

L Belcour, C Soler, K Subr, N Holzschuch… - ACM Transactions on …, 2013 - dl.acm.org
The rendering of effects such as motion blur and depth-of-field requires costly 5D integrals.
We accelerate their computation through adaptive sampling and reconstruction based on …

Subsampling bias and the best-discrepancy systematic cross validation

L Guo, J Liu, R Lu - Science China Mathematics, 2021 - Springer
