Abstract
A method of encapsulating an encoded bitstream representing one or more images, the encapsulated bitstream comprising a data part and a metadata part. The method including providing image item information identifying a portion of the data part representing a sub-image or an image of a single image; providing image description information comprising parameters including display parameters and/or transformation operators relating to one or more images and outputting said bitstream together with said provided information as an encapsulated data file, wherein the image description information is stored in the metadata part.
Claims14
A method of encapsulating an encoded bitstream representing one or more images, the encapsulated bitstream comprising a data part and a metadata part, the method comprising:
- providing image item information identifying a portion of the data part representing a sub-image or an image of a single image;
- providing image description information comprising parameters including display parameters and/or transformation operators relating to one or more images and
- outputting the bitstream together with the provided information as an encapsulated data file;
- wherein the image description information is stored in the metadata part.
The method according to claim 6, wherein a box stored in the metadata part include at least one transformation operator and/or at least one display parameter.
A method of processing an encapsulated data file comprising a data part and a metadata part, including an encoded bitstream corresponding to one or more images in the data part, and information in the metadata part including image or sub-image description information comprising parameters including display parameters and/or transformation operators relating to one or more image or sub-images, the method comprising:
- selecting an image or a sub-image of interest,
- identifying, from the referenced image or sub-image description information, associated display parameters and/or transformation operators from the meta data part;
- in the case that transformation operators have been identified, applying the transformation to the image or sub-image, and displaying the image or sub image eventually transformed, according to the display parameters.
