1. A filtering method for encoding a video, comprising:
determining filtering parameters of an adaptive filter;
filtering input samples by using the adaptive filter according to the filtering parameters and edge information to obtain filtered samples;
determining first filtering parameters, wherein the first filtering parameters are a portion of the filtering parameters which need to be encoded;
encoding the first filtering parameters, wherein the first filtering parameters are signaled in a video bitstream; wherein the adaptive filter is a neural network filter.
