20080232705 | METHOD AND APPARATUS FOR IMAGE ENCODING AND IMAGE DECODING - Provided are a method and apparatus for image encoding which improves encoding efficiency in accordance with image characteristics by performing prediction in lines and performing a one-dimensional transformation in lines on an input image, and a method and apparatus for image decoding. Encoding efficiency of an image may be improved by generating a prediction sub residual block using neighboring residues and performing a one-dimensional discrete cosine transformation (DCT) on a difference residual block which is a difference between an original sub residual block and the prediction sub residual block. | 09-25-2008 |
20080310744 | METHOD AND APPARATUS FOR INTRAPREDICTION ENCODING/DECODING USING IMAGE INPAINTING - A method and apparatus for intraprediction encoding/decoding is provided. The method includes performing image inpainting based on pixels included in a previously encoded region of a current picture among pixels that are adjacent to a boundary between a current block and the previously encoded region of the current picture in order to predict the current block, and performing prediction encoding on the current block using the prediction result. Thus, a new intraprediction mode in which the current block can be accurately predicted can be provided. | 12-18-2008 |
20110211757 | COLOR IMAGE ENCODING AND DECODING METHOD AND APPARATUS USING A CORRELATION BETWEEN CHROMINANCE COMPONENTS - A color image encoding and decoding method and apparatus use a correlation between chrominance components in order to improve coding efficiency.
