Method and apparatus for image encoding/decoding using prediction of filter information

PURPOSE: An image encoding/decoding method using filter information prediction and a device thereof are provided to reduce the quantity of transmission data. CONSTITUTION: An encoder and a decoder predict the filter information used for a target restoration image from a predetermined layer(S510). The encoder and the decoder filter the target restoration image by using the predicted filter information(S520). The filter information includes calculated filter information and/or predetermined filter information.
