Claim 0:
1. A method for denoising a video comprising multiple frames, the method comprising:
obtaining, at a first denoiser, a central frame, an input frame that is temporally precedent to the central frame, and a second input frame that is temporally precedent to the input frame;
obtaining, at a second denoiser, the central frame, the input frame, and a third input frame that is temporally subsequent to the central frame;
obtaining, at a third denoiser, the central frame, the third input frame, and a fourth input frame that is temporally subsequent to the third input frame;
obtaining, at a fourth denoiser, a first denoised frame from the first denoiser, a second denoised frame from the second denoiser, and a third denoised frame from the third denoiser;
denoising the first denoised frame, the second denoised frame, and the third denoised frame, wherein the denoising is based on a multi-scale encoder-decoder architecture, and wherein the multi-scale architecture includes a plurality of skip-connections that forward an output of an encoder layer directly to an input of a corresponding decoder layer; and
outputting a fourth denoised frame based on the first denoised frame, the second denoised frame, and the third denoised frame.
