Method and apparatus for video encoding using dynamic-range trasformation method and apparatus for video decoding using dynamic-range transformation

摘要

Inter prediction is performed on the current frame using intra prediction and motion estimation using the image data obtained by converting the dynamic range of the current frame based on the content of the input video, and residual data generated by intra prediction and inter prediction, A method of encoding a video using dynamic range conversion based on content, which performs frequency conversion on a transform coefficient generated by a frequency transform and quantizes the transform coefficient generated by frequency transform to perform entropy encoding on a quantized transform coefficient.
