Abstract
A method of decoding an image, includes obtaining at least one offset for a picture, deriving a variable for scaling for the picture based on the at least one offset, and performing inter prediction based on the variable for scaling for the picture. The at least one offset is defined with a direction of scaling.
Claims7
A method for decoding an image, the method comprising:
- receiving a bitstream for the image;
- decoding information on partitioned regions for the image included in the bitstream;
- obtaining a plurality of partitioned regions included in the image based on the information on partitioned regions;
- and
- reconstructing the image by decoding each of the plurality of partitioned regions,
- wherein the reconstructing the image comprises generating a prediction block for a block included in the image,
- wherein each partitioned region comprises a plurality of default encoding part, the default encoding part is selected from a plurality of candidate default encoding parts, each candidate default encoding parts is composed of one or more encoding sub-unit, and
- wherein the bitstream comprises information on yaw rotation of the image.
