    Abstract: A video encoding method and apparatus are provided. The video encoding method includes determining whether a current block includes an affine-transformation object having an affine transformation; if the current block includes an affine-transformation object, generating a prediction block by performing affine transformation-based motion compensation on the current block in consideration of an affine transformation of the affine-transformation object; and if the current block does not include any affine-transformation object, generating a prediction block by performing motion vector-based motion compensation on the current block using a motion vector of the current block. Therefore, it is possible to achieve high video encoding/decoding efficiency even when a block to be encoded or decoded includes an affine transformation.

    Abstract: An apparatus for coding an image which may effectively code the image and an apparatus for decoding an image which may decode the effectively coded image. The apparatus for coding the image includes: an input image segmentation unit to segment an input image into a plurality of image blocks including a first image block and a second image block; a waveform information generation unit to select a plurality of reference pixels from among pixels included in the first image block, generate first waveform information about the first image block based on a pixel value difference between the selected plurality of reference pixels, and generate second waveform information about the second image block based on a pixel value difference between the pixels included in the second image block; and coding unit to code an image included in the second image block based on the first waveform information and second waveform information.
