    摘要: A method and a device for performing inter prediction of a video, and encoding and decoding a video using an inter prediction, are provided. A video prediction method includes: determining reference information indicating at least one reference image for inter predicting an image; determining a first reference list and a second reference list, each of which includes the determined reference information and a reference order of the at least one reference image; and if the determined reference information indicates only images for uni-directional prediction, generating a reconstructed image by referring to images indicated by the first and second lists in a same reference order.

    摘要: Provided are methods and apparatuses for transforming and inverse-transforming an image. The method of transforming an image includes: generating a substituted N×N transformation matrix by substituting elements of an N×N transformation matrix used for a 1-dimensional (1D) discrete cosine transform (DCT) of a N×N block of the image with values based on N variables, where N is an integer; obtaining a multiplication matrix of the substituted N×N transformation matrix and a transposed matrix of the substituted N×N transformation matrix; obtaining the N variables that enable a sum of squares of elements excluding diagonal components of the obtained multiplication matrix to be a minimum; and transforming the N×N block by using the substituted N×N transformation matrix, which is substituted with the values based on the obtained N variables.
