Abstract
An image decoding method performed by a decoding apparatus according to the present invention comprises the steps of: generating a reconstruction area for a target area within a current picture; deriving a predetermined plurality of basic filters for the target area; updating at least one basic filter among the plurality of basic filters; receiving weight information for each of the basic filters; determining a merge filter for the target area on the basis of the basic filters and the weight information; and generating a modified reconstruction area by performing filtering on the target area on the basis of the filter coefficient of the determined merge filter. The present invention allows updating with filter information suitable for improving the visual quality of the target area and can thereby improve the accuracy of filtering and overall coding efficiency.
