摘要： Provided is a motion compensation method and apparatus. The motion compensation method includes performing register setting for motion compensation of an mth macroblock of a current image, performing prediction for the mth macroblock simultaneously with performing register setting for motion compensation of an (m+1)th macroblock, and performing reconstruction for the mth macroblock based on a prediction result simultaneously with performing prediction for the (m+1)th macroblock. By parallely processing motion compensation on macroblocks, the amount of time required for motion compensation of the macroblocks can be reduced.

摘要： An apparatus and method for coding and decoding an image are provided. The apparatus for coding the image includes a spatio-temporal information prediction/compensation unit, a recovered image processor, a residue generator, a quantizer, and an entropy encoder. The spatio-temporal information prediction/compensation unit generates a predicted image by predicting and compensating spatio-temporal information including at least one of temporal prediction information from a current image and a recovered previous image, and spatial prediction information from a recovered current image. The recovered image processor performs a spatio-temporal noise removal process on the recovered current image using the spatio-temporal information, and stores the resulting noise-removed image. The residue generator generates a residue image obtained by subtracting the predicted image from the input image, and the quantizer outputs quantized coefficients by quantizing the residue image. The entropy encoder generates a bit stream by entropy coding the quantized coefficients.

摘要： A method and apparatus for encoding and decoding image data. The method of encoding image data includes spatially predicting pixel values of a one-dimensional block of an image using blocks spatially adjacent to the one-dimensional block or temporally predicting the pixel values of the one-dimensional block using a temporally previous frame; transforming and quantizing the pixel values of the one-dimensional block; and generating bit streams for a one-dimensional conversion block when the transformed and quantized one-dimensional block is defined as the one-dimensional conversion block. Therefore, since the method and apparatus encode and decode image data in one-dimensional block units, real-time encoding and decoding can be achieved. In addition, compression efficiency can be enhanced while minimizing visual degradation of image quality.
