Abstract
A system for processing video. The system may include a video camera, a processing unit, and a video display, the video camera being configured to generate a plurality of consecutive luminance frames, including a last frame and a plurality of preceding frames. The processing unit may be configured to: shift the plurality of preceding frames, to register the preceding frames with the last frame to form a plurality of shifted frames, take a Fourier transform of each of the plurality of frames, to form a corresponding plurality of initial Fourier transform frames, iteratively update the plurality of Fourier transform frames by, on the (n+1)th iteration of a plurality of iterations, replacing each Fourier transform frame with a linear combination of the Fourier transform frames of the nth iteration, the Fourier transform frames of the 0th iteration being the initial Fourier transform frames.
