1. A decoding apparatus for image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
obtain image information including residual information and reference picture-related information through a bitstream;
derive at least one reference picture, based on the reference picture-related information;
generate reconstructed samples of a current picture, based on the residual information and the at least one reference picture; and
generate modified reconstructed samples, based on an in-loop filtering process for the reconstructed samples,
wherein the image information includes a sequence parameter set (SPS),
wherein based on whether resampling for the at least one reference picture is enabled, it is determined whether the SPS includes additional virtual boundaries-related information,
wherein the SPS includes an SPS virtual boundaries present flag related to whether the SPS includes the additional virtual boundaries-related information, and
wherein based on that the resampling for the at least one reference picture is enabled, a value of the SPS virtual boundaries present flag is determined to be 0.
