Abstract: A video encoding and decoding methods and apparatuses for performing the methods thereof are provided. The video encoding method includes: determining a region in a current image having a change in at least one of a scale and an angle with respect to a reference image; generating variation information representing a variation in at least one of the scale and the angle between the region in the current image and a reference region in the reference image corresponding to the region in the current image; and encoding residual information representing a difference between a predicted sample value from the reference image and a sample value of the current image based on the generated variation information.

Abstract: An inter-view video decoding method may include determining a disparity vector of a current second-view depth block by using a specific sample value selected within a sample value range determined based on a preset bit-depth, detecting a first-view depth block corresponding to the current second-view depth block by using the disparity vector, and reconstructing the current second-view depth block by generating a prediction block of the current second-view depth block based on coding information of the first-view depth block.

Abstract: An inter-layer video decoding method is described including reconstructing a color image and a depth image of a first layer based on encoding information about the color image and the depth image of the first layer obtained from a bitstream. When it is determined that a prediction mode of a current block of a second layer image to be decoded is a view synthesized prediction mode based on an image synthesized from the first layer image a determination is made whether to perform luminance compensation on the second layer current block to be reconstructed. Use of the view synthesized prediction mode to reconstruct the second layer current block depends on the luminance compensation determination.
