METHOD FOR ENCODING/DECODING IMAGE AND DEVICE FOR SAME

摘要

Disclosed in the present invention are a method for encoding/decoding an image and a device for same. Particularly, a method for decoding an image may comprise the steps of: parsing a filter index from a bitstream outputted from an encoder; determining a filter set using the filter index, from among a plurality of filter sets belonging to a predetermined filter bank; deriving a filter coefficient based on a coefficient for filtering, defined by the filter set, which has been determined by the filter index; and applying filtering to a recovered image obtained using a prediction signal and a differential signal, by using the derived filter coefficient.
