1. A computer-implemented method, comprising:
locating, by a backward projection pass and based at least in part on at least one motion vector, at least one pixel of a stratum comprising an array of adjacent pixels in a current frame of a video having an identified matching surface in at least one previous frame of the video;
determining lighting data based at least in part on visibility buffer information corresponding to the at least one previous frame and a G-buffer for the current frame;
determining, based at least in part on the lighting data, one or more differences between corresponding pixels of the current frame and the at least one previous frame; and
rendering an image based at least in part on the one or more differences.
