Method and apparatus for video coding on pixel-wise prediction
A pixel-based video encoding apparatus includes a block prediction unit, a residual image generation unit, a pixel prediction unit, and an entropy-coding unit. The block prediction unit performs temporal or spatial prediction between a reference image and a current image in order to generate a prediction block corresponding to a current block to be encoded. The residual image generation unit generates a residual image block composed of a residual signal corresponding to a difference between pixels of the prediction block and pixels of the current block. The pixel prediction unit determines whether to apply differential pulse coded modulation to each of pixels of the residual image block based on a rate distortion optimization value. The entropy-coding unit performs entropy-coding on the residual image block.
