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.
Claims10
An image decoding method, comprising:
- obtaining resizing information for resizing an image;
- and
- resizing the image to generate a resized image based on the resizing information,
- wherein the resizing information specifies whether to perform the resizing and a direction of the resizing.
An image encoding method, comprising:
- determining resizing information for resizing an image;
- resizing the image to generate a resized image based on the resizing information;
- and
- encoding the resizing information,
- wherein the resizing information specifies whether to perform the resizing and a direction of the resizing.
A method of transmitting encoded data which is generated by an image encoding method, the image encoding method comprising:
- determining resizing information for resizing an image;
- resizing the image to generate a resized image based on the resizing information;
- and
- encoding the resizing information,
- wherein the resizing information specifies whether to perform the resizing and a direction of the resizing.
A non-transitory computer-readable recording method storing encoded data which is generated by an image encoding method, the image encoding method comprising:
- determining resizing information for resizing an image;
- resizing the image to generate a resized image based on the resizing information;
- and
- encoding the resizing information,
- wherein the resizing information specifies whether to perform the resizing and a direction of the resizing.
