Abstract
The present invention relates to a method for performing bi-prediction using a template-based weight, comprising the steps of: determining a template region for performing bi-prediction of a current block; calculating an uncorrelation factor on the basis of the template region, wherein the uncorrelation factor denotes a value indicating the uncorrelation between a template of the current block and a template of a reference block; determining a first weight parameter of the current block on the basis of the uncorrelation factor; and obtaining a first prediction value of the current block using the weight parameter.
