1. An image decoding method performed by a decoding apparatus, the method comprising:
obtaining image information including residual information through a bitstream;
generating reconstructed samples of a current picture, based on the residual information;
performing an in-loop filtering process on the reconstructed samples of the current picture to generate modified reconstructed samples; and
determining whether the in-loop filtering process is performed across virtual boundaries,
wherein the image information includes a sequence parameter set (SPS) and picture header information,
wherein based on whether reference picture resampling is enabled, whether the SPS includes additional virtual boundaries-related information is determined,
wherein based on that the reference picture resampling is enabled, the SPS does not include the additional virtual boundaries-related information, and the picture header information includes the additional virtual boundaries-related information, and
wherein the additional virtual boundaries-related information comprising information on a number of the virtual boundaries and information on positions of the virtual boundaries is included in the picture header information.
