Image encoding/decoding method and apparatus
The present invention relates to an image encoding/decoding method and apparatus, A method of decoding an image according to an exemplary embodiment of the present invention comprises: decoding transformation information; creating at least one transformed reference picture by applying the transformation information to at least one reference picture organized in a reference picture list; inserting the at least one transformed reference picture into the reference picture list; and performing motion compensation by using the reference picture list.
1. A method of decoding an image, the method comprising:
decoding transformation information for a current block;
generating a first reference picture and a second reference picture list for the current block;
generating at least one transformed reference picture by applying the transformation information to at least one reference picture included in a first reference picture list;
including the at least one transformed reference picture into the first reference picture list;
generating a first prediction signal of the current block by using the transformed reference picture of the first picture list;
generating a second prediction signal of the current block by using a non-transformed reference picture of the second reference picture list; and
generating a final prediction signal of the current block by applying a weighted sum to the first prediction signal and the second prediction signal.
2. The method according to claim 1 , further comprising:
wherein the step of including the at least one transformed reference picture into the first reference picture list further comprises:
determining whether to include the transformed reference picture into the first reference picture list on the basis of transformed reference picture utilization information; and
including the at least one transformed reference picture into the first reference picture list according to the determination result.
3. The method according to claim 1 , wherein the transformed reference picture is included after the at least one reference picture in the first reference picture list.
4. The method according to claim 1 , wherein the at least one transformed picture is generated using a reference picture at a predetermined position in the first reference picture list.
