Abstract: Embodiments of the present disclosure provide a loop filtering method, including: determining a reference image block corresponding to a to-be-processed image block in an adjacent reference frame in a time domain, and predicting the loop filtering enabling probability of the to-be-processed image block based on the result of loop filtering of the reference image block; determining spatial coding information of the to-be-processed image block, the spatial coding information being used to characterize texture complexity of the to-be-processed image block; and making a loop filtering decision for the to-be-processed image block in response to the spatial coding information and the loop filtering enabling probability meeting preset filtering conditions.
