摘要： A method and apparatus for video encoding/decoding are provided to improve compression efficiency by generating a prediction block using an intra-inter hybrid predictor. A video encoding method includes dividing an input video into a plurality of blocks, forming a first predictor for an edge region of a current block to be encoded among the divided blocks through intraprediction, forming a second predictor for the remaining region of the current block through interprediction, and forming a prediction block of the current block by combining the first predictor and the second predictor.

摘要： An apparatus and a method for detecting an edge of a three-dimensional image. A scan-line approximation unit creates an approximated quadratic curve with regard to each scan-line corresponding to each surface of the three-dimensional image by scanning the three-dimensional image in several directions of a row, a column and both diagonal lines. A curvature value calculation unit calculates approximated curvature values with regard to each division point regarded as different surfaces of the three-dimensional image on the quadratic curve. An edge decision unit decides an edge by comparing the calculated curvature values of the division points with a threshold. According to the above apparatus and the method for detecting the edge of the three-dimensional image, both a jump edge and a crease edge can be detected through one threshold. The method of detecting the edge can detect all edges according to the characteristic of the object of the three-dimensional image by using one threshold, thus the edge can be quickly and more accurately detected. Furthermore, the capability of the entire system can be improved by using information gained during the process of detecting the edge in a pre-process and a post-process.

摘要： Provided are an encoding and decoding method and an apparatus for implementing the same in which a processing order for predetermined-size blocks included in a macroblock is defined in order to efficiently use spatial correlation in an image. After a macroblock is divided into first blocks of a predetermined size and motion compensation is performed on each of the first blocks, a second-block processing order for sequentially processing second blocks included in a current first block is determined in order to process a residue between a motion compensation value of the current first block and the current first block in units of the second blocks having a smaller size than that of the current first block.
