摘要： An image processing apparatus is disclosed. The present image processing apparatus comprises: a memory for storing a low dynamic range (LDR) image and a processor for adjusting the brightness of the LDR image by means of a pixel-specific brightness ratio identified using a first parameter, and acquiring a high dynamic range (HDR) image by adding or subtracting a pixel-specific correction value identified using a second parameter in the brightness-adjusted LDR image.

摘要： An image processing apparatus is disclosed. The present image processing apparatus includes an input unit to which an image is input; and a processor which extracts visual characteristics by reducing an input image and obtains a high-definition image by reflecting extracted visual characteristics on the input image. The disclosure relates to an artificial intelligence (AI) system and application thereof that simulate functions such as cognition and decision-making of a human brain using a machine learning algorithm such as deep learning.

摘要： A method and apparatus for encoding and decoding motion information. The encoding method includes determining whether motion information of spatial prediction units that are spatially collocated to a current prediction unit and motion information of temporal prediction units that are temporally collocated to the current prediction are available; when the number of the motion information of the spatial prediction units and the motion information of the temporal prediction units is less than a predetermined number, generating additional candidate motion information by using the available motion information of the spatial prediction units and the motion information of the temporal prediction units such that the total number of pieces of candidate motion information is the predetermined number; and decoding motion information of the current prediction unit by using the 'n' pieces of motion information.

摘要： A method of decoding a video includes obtaining syntax for determining an initial value of a quantization parameter (QP) used to perform inverse quantization on coding units included in a slice segment, from a bitstream; obtaining a slice-level initial QP for predicting the QP used to perform inverse quantization on the coding units included in the slice segment, based on the obtained syntax; and obtaining a predicted QP of a first quantization group of a parallel-decodable data unit included in the slice segment, by using the slice-level initial QP.

摘要： A method of encoding an image by transforming a group of prediction units into a frequency domain. A prediction unit may be predicted by using prediction values of the prediction units in the group of prediction units, instead of pixels generated by encoding and then restoring the other prediction units in the group of prediction units. Thus, an encoding compression ratio may be increased as a result of grouping the prediction units.

摘要： A method of decoding a video, which performs deblocking filtering based on coding units. The corresponding emcoding method includes determining a filtering boundary on which deblocking filtering is to be performed based on at least one data unit from among coding units that are hierarchically configured according to depths indicating a number of times at least one maximum coding unit is spatially spilt, and prediction units and transformation units respectively for prediction and transformation of the coding units, determining filtering strength at the filtering boundary based on a prediction mode of a coding unit to which adjacent pixels belong based on the filtering boundary, and transformation coefficient values of pixels adjacent to the filtering boundary, and performing deblocking filtering based on the determined filtering strength.
