摘要： A method and an apparatus are disclosed for video coding using an improved in-loop filter. The video coding method and the apparatus generate a residual frame from a reconstructed frame using a deep learning model. The video coding method and the apparatus improve performance of an in-loop filter by approximating an original residual frame by applying the generated residual frame to a linear model.

摘要： A method and an apparatus for video coding using a deep learning-based in-loop filter for inter-prediction are disclosed. The video coding method and the apparatus utilize a deep learning-based in-loop filter for inter-prediction of a predictive frame (P-frame) and a bipredictive frame (B-frame) in order to mitigate various levels of image distortion according to a QP (quantization parameter) value present in the P-frame and the B-frame.

摘要： A video coding method and an apparatus for refining predicted signals in intra prediction are disclosed. The video coding method and apparatus generate refined prediction signals approximating original video signals from predicted signals of intra prediction using a variable and fixed coefficient-based deep learning model to reduce the amount of data for residual signals, which are to be encoded.

摘要： A video encoding method and a video decoding method is provided for generating improved picture quality for a current frame and improving encoding efficiency. The video encoding method and the video decoding method further include an in-loop filter that detects a reference region from a current frame and a reference frame using a deep learning-based detection model and then combines the detected reference region with the current frame.

摘要： A method is disclosed for modifying a decoder-side motion vector list in inter prediction. A video coding method and an apparatus use a template matching method or a bilateral matching (BM) method in a merge mode and an advanced motion vector prediction (AMVP) mode of inter prediction. The video coding method and the apparatus perform at least one of adding, pruning, or reordering candidates with respect to a motion vector list at the decoder side.
