1. A method, comprising: generating a current frame of image data in a memory; and for each pixel in the current frame of image data: sampling a resolved pixel color for a corresponding pixel in a previous frame of image data stored in the memory; adjusting the resolved pixel color based on a statistical distribution of color values for a plurality of samples in the neighborhood of the pixel in the current frame of image data to generate an adjusted pixel color, comprising: calculating a mean color value based on the color values for a plurality of samples in the neighborhood of the pixel; calculating a variance for each color component based on the color values for the plurality of samples in the neighborhood of the pixel; and generating an axis-aligned bounding box (AABB) based on the mean color value and a standard deviation from the mean color value, wherein the standard deviation from the mean color value is calculated based on the variance, for each color component; and blending a color value for the pixel in the current frame of image data with the adjusted pixel color to generate a resolved pixel color for the pixel in the current frame of image data.
