Abstract
To generate photo-realistic images, modern renderers generally use stochastic algorithms such as the path-tracing algorithm. These algorithms can produce high-quality images but may require a long computation time. Therefore, rendering is generally stopped after a given amount of time and the output image may not be fully converged. In this case, the resulting variance can be seen as noise.
