  • Publication number: 20190158834
    Abstract: A video encoding apparatus includes at least one processor. The at least one processor is configured to adjust a size of a first quantization parameter with reference to a characteristic of quantization coefficients generated from input data by using the first quantization parameter, to determine the first quantization parameter of the adjusted size as a final quantization parameter, and to quantize the input data by using the final quantization parameter to generate output data.

  • Publication number: 20190124348
    Abstract: An image encoder for outputting a bitstream by encoding an input image includes a predictive block, a machine learning based prediction enhancement (MLBE) block, and a subtractor. The predictive block is configured to generate a prediction block using data of a previous input block. The MLBE block is configured to transform the prediction block into an enhanced prediction block by applying a machine learning technique to the prediction block. The subtractor is configured to generate a residual block by subtracting pixel data of the enhanced prediction block from pixel data of a current input block.

  • Publication number: 20140348436
    Abstract: The inventive concept relates to an encoding method of encoding image data of a frame including a plurality of image blocks. The encoding method includes selecting a first image block as the main image block of a first window, selecting a first window having to perform a plurality of loop filtering schemes on image data of the selected window. The loop filtering schemes includes a deblocking filtering, a sample adaptive offset filtering, and an adaptive loop filtering. The perimeter of the selected first window does not coincide with the perimeter of the first image block.
