Method and apparatus for generating a reference frame and method and apparatus for encoding/decoding image using the same
A method for encoding pixels in an image, includes: encoding an offset to be applied to a reference frame; generating predicted pixels of the pixels in the image, based on interpolating pixels in the reference frame and then adding the offset to the interpolated pixels; and encoding residual signals that are differences between the pixels in the image and the predicted pixels, wherein the encoding of the residual signals comprises: skipping both transform and quantization with respect to residual signals of which an encoding scheme corresponds to skipping of both transform and quantization, the encoding scheme related to transform and quantization, skipping transform and performing quantization with respect to residual signals of which the encoding scheme corresponds to skipping of transform, and performing transform and quantization with respect to residual signals of which the encoding scheme corresponds to skipping neither transform nor quantization.
