METHOD AND APPARATUS FOR ENCODING VIDEO BY USING DYNAMIC-RANGE TRANSFORMATION, AND METHOD AND APPARATUS FOR DECODING VIDEO BY USING DYNAMIC-RANGE TRANSFORMATION |
摘要 |
Provided is a method and apparatus for encoding a video by using dynamic range transformation based on content and a method and apparatus for decoding a video by using dynamic range transformation based on content. The encoding method includes: performing inter prediction, through motion estimation, and intra prediction for a current region using image data in which a dynamic range of the current region is transformed based on content of an image of input video; performing transformation on residual data generated by the intra prediction and the inter prediction and performing quantization on a transformation coefficient generated by the transformation; and performing entropy encoding on the quantized transformation coefficient. |
