Abstract: Encoding and decoding using frequency-domain denoising are provided. Encoding and decoding using frequency-domain denoising may include identifying a current source block from a current source frame from a source video stream, generating a prediction block for the current source block, generating a source transform block by transforming the current source block into the frequency domain, generating a prediction transform block by transforming the prediction block into the frequency domain, generating a denoised transform block based on the source transform block and the prediction 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 prediction block, generating an encoded block by encoding the residual block, and outputting or storing the encoded block.

Abstract translation: 提供使用频域去噪的编码和解码。 使用频域去噪的编码和解码可以包括从源视频流识别来自当前源帧的当前源块，生成用于当前源块的预测块，通过将当前源块变换为频率来生成源变换块 通过将预测块变换为频域来生成预测变换块，基于源变换块和预测变换块生成去噪变换块，通过逆变换去噪变换块来生成去噪块，生成残留块 基于去噪块和预测块之间的差异，通过对残差块进行编码生成编码块，并输出或存储编码块。
