Abstract
A method for determining whether a pixel of a computer-rendered image is a firefly includes: dividing a plurality of samples originating from the pixel, into first and second subsets; identifying whether the pixel is an outlier based on variance data of the first subset; identifying whether the pixel is an outlier based on variance data of the second subset. The pixel is determined as not a firefly in response to both the pixel being identified as an outlier based on the variance data of the first subset, and the pixel being identified as an outlier based on the variance data of the second subset. The pixel is determined as a firefly in response to the pixel being not identified as an outlier based on the variance data of the first (second) subset and being identified as an outlier based on the variance data of the second (first) subset.
