Statistical Hypothesis Testing for Assessing Monte Carlo Estimators: Applications to Image Synthesis
13 years 11 months ago
Image synthesis algorithms are commonly compared on the basis of running times and/or perceived quality of the generated images. In the case of Monte Carlo techniques, assessment ...
