1. A method for performing a random parameter filter, comprising the steps of:

  • rendering one or more image samples at a given sampling rate;

    storing a vector of a plurality of scene features for each image sample;

    saving one or more random parameters for each image sample used to calculate the image sample by a rendering system;

    choosing the one or more image samples to process;

    performing pre-processing on the one or more image samples;

    calculating a dependency of a color and a feature of the one or more random parameters and one or more rendering system inputs to obtain a calculated dependency;

    using the calculated dependency to determine a weight for each scene feature to obtain dependency information;

    modifying the one or more image samples using the dependency information to obtain a final modified sample;

    filtering the final modified sample to produce one or more pixels; and

    outputting a final image.
