METHOD FOR ENDCODING IMAGE DATA AND METHOD FOR AND DECODING IMAGE DATA BASED ON SCALE AND ANGLE VARIATION INFORMATION AND APPARATUS FOR ENCODING IMAGE DATA AND APPARATUS FOR DECODING IMAGE DATA BASED ON SCALE AND ANGLE VARIATION INFORMATION
Disclosed is a method for video decoding, which determines a variation area of a current image having change in at least one among size and angle from a reference image; generates variation information presenting at least one variation among the size and angle between a variation area and a reference area of the reference image corresponding to a variation area, and encodes residue information presenting difference between a sample value predicted in the reference image and the sample value of the current image based on the generated variation information.
