摘要： Provided are a method of interpolating an image by determining interpolation filter coefficients, and an apparatus for performing the same. The method includes: differently selecting an interpolation filter, from among interpolation filters for generating at least one sub-pel-unit pixel value located between integer-pel-unit pixels, based on a sub-pel-unit interpolation location and a smoothness; and generating the at least one sub-pel-unit pixel value by interpolating, using the selected interpolation filter, pixel values of the integer-pel-unit pixels.

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.
