Abstract
An image processing method is disclosed, comprising comparing a first image and a modified second image, the modified second image comprising a copy of the first image in which at least one pixel value of one or more pixels have been modified, and based on the result of the comparison, generating first image reconstruction information which can be combined with the modified second image to reconstruct the first image. A corresponding image reconstruction method comprises combining the image reconstruction information with the modified second image to reconstruct the first image. Apparatus for implementing the methods is also disclosed.
Claims20
A method for processing an image, the method comprising:
- comparing a first image and a modified second image, the modified second image comprising a copy of the first image in which at least one pixel value of at least one replaced pixel has been modified;
- and
- based on the result of the comparison, generating separate image reconstruction information for each layer of additional content which can be combined with the modified second image to reconstruct the first image.
A method for reconstructing an image, the method comprising:
- obtaining separate image reconstruction information for each layer of additional content associated with a modified second image;
- and
- combining the separate image reconstruction information for each layer of the additional content with the modified second image to reconstruct a first image, the modified second image comprising a copy of the first image in which at least one pixel has been replaced.
An apparatus for processing an image, the apparatus comprising:
- at least one processor;
- and
- memory adapted to store computer program instructions,
- wherein the at least one processor is configured to:
- compare a first image and a modified second image, the modified second image comprising a copy of the first image in which at least one pixel has been replaced, and
- based on the result of the comparison, generate separate image reconstruction information for each layer of additional content which can be combined with the modified second image to reconstruct the first image.
