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; 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.
