FILTERING WITH SIDE-INFORMATION USING CONTEXTUALLY-DESIGNED FILTERS

Original (Chinese)

A filter bank comprising filters is obtained. For pixels of a degraded frame, respective sets of combining scalars for combining the filters of the filter bank are obtained. For the pixels of the degraded frame, respective pixel-specific filters are obtained by combining the filters of the filter bank using the respective sets of combining scalars. A restored frame is obtained by filtering the pixels of the degraded frame using the respective pixel-specific filters. The respective sets of combining scalars may be obtained using a machine-learning model that receives the degraded frame as an input, where the machine-learning model is a convolutional neural network. The machine-learning model may be trained to minimize an error between restored frames and corresponding source frames.
