Abstract
In a method for image encoding of a digitalized image, in a method for image decoding of a digitalized image, and in an arrangement for the implementation of the methods, both in motion estimating as well as in motion compensation, a padding is implemented only for picture elements of an object edge image block that are located within an image object. No padding is implemented for other picture elements located outside the image object.
Claims12
A method for image encoding of a digitalized image having an arbitrary number of picture elements, comprising the steps of:
- identifying in the image at least one image object that comprises an arbitrary number of picture elements;
- dividing the image into image blocks;
- implementing a motion estimation for the image blocks;
- implementing a padding in the motion estimation of an object edge image block that comprises at least one object edge of the image object;
- and
- only implementing the padding with respect to picture elements that are located within the image object.
A method for image decoding of a digitalized image having an arbitrary number of picture elements, comprising the steps of:
- providing the image with at least one image object that comprises an arbitrary number of picture elements;
- providing the image with image blocks;
- implementing a motion compensation for the image blocks;
- implementing a padding in the motion compensation of an object edge image block that comprises at least one object edge of the image object;
- and
- only implementing the padding with respect to picture elements that are located within the image object.
An apparatus for image encoding of a digitalized image having an arbitrary number of picture elements, comprising:
- a processor unit that is configured such that at least one image object that comprises an arbitrary number of picture elements is identified in the image;
- the image is divided into image blocks;
- a motion estimation is implemented for the image blocks;
- a padding is implemented in the motion estimation of an object edge image block that comprises at least one object edge of the image object;
- and
- the padding is only implemented with respect to picture elements that are located within the image object.
