Abstract: An example method of video coding includes receiving a video bitstream for a plurality of encoded pictures. The method also includes deriving, using a first type of frame interpolation, a reconstruction picture for an encoded picture of the plurality of encoded pictures, and determining, based on a signaled indicator in the video bitstream, whether to apply loop filtering to the reconstruction picture. When the signaled indicator has a first value, a decoded picture for the encoded picture is derived by applying one or more loop filters to the reconstruction picture. When the signaled indicator has a second value, the decoded picture is derived without applying the one or more loop filters to the reconstruction picture.

Abstract: Provided are a waterborne polyurethane (WPU) and a preparation method thereof, and a waterborne scratch-off ink and a preparation method thereof. A chain end group or side group of the WPU contains a longer alkyl chain. When the WPU is used in the preparation of the waterborne scratch-off ink, microphase separation may occur during the film-forming process owing to a hydrophobic/hydrophilic interaction between the non-polar long-chain alkyl and polar groups in WPU molecular, resulting in an incomplete film structure, which is beneficial to make the ink be scratched off.
