摘要： Encoding using frequency-domain denoising includes identifying a current source block from a current source frame from a source video stream, generating a predicted block for the current source block, generating a source transform block by transforming the current source block into the frequency domain, generating a predicted transform block by transforming the predicted block into the frequency domain, generating a denoised transform block based on the source transform block and the predicted transform block, generating a denoised block by inverse transforming the denoised transform block, generating a residual block based on a difference between the denoised block and the predicted block, generating an encoded block by encoding the residual block, and outputting or storing the encoded block.
