    摘要: Provided are encoding and decoding methods and apparatuses for a video by selectively determining and using a scan mode. The video encoding method includes: generating transformation coefficients by performing transformation based on a transformation unit to encode an image; determining a scan mode, from among a plurality of scan modes, indicating a scanning direction of the generated transformation coefficients, based on characteristics of the transformation coefficients; and determining and outputting an encoding order of the generated transformation coefficients based on the scanning direction of the determined scan mode.

    摘要: An apparatus and method for intra-predicting an image are provided. The method includes: obtaining, based on restored neighboring pixels of a chrominance block and restored neighboring pixels of a luminance pixel corresponding to the chrominance block, parameters representing a correlation between the chrominance block that is to be intra-predicted and a luminance block; and predicting, using the parameters, the chrominance block from the luminance block, wherein the obtaining the parameters includes performing a predetermined operation on the restored neighboring pixels of the chrominance block and the restored neighboring pixels of the luminance block, and wherein the predetermined operation comprises an adaptive scaling process of changing bit depths of the parameters to reduce a size of a look-up table and prevent an occurrence of overflow.

    摘要: An encoding method using a skip mode is provided. The method includes obtaining a plurality of motion information candidates of a current predictor by using at least one predictor which relates to the current predictor; determining a candidate that is most likely to be selected from among the obtained plurality of motion information candidates as a most probable prediction candidate, based on a predetermined standard; and when a prediction mode of the current predictor corresponds to a most probable skip mode when using the determined most probable prediction candidate, encoding a flag which indicates the most probable skip mode.
