/Method And Apparatus For Encoding/decoding Image Using Quantization Parameter, And Recording Medium Storing Bitstream
Abstract
There is provided an image encoding/decoding method and apparatus. The image decoding method comprises decoding size information of a quantization group from a bitstream, acquiring a delta quantization parameter of a current block on the basis of the size information of the quantization group, and deriving a quantization parameter for the current block on the basis of the delta quantization parameter.
