Method and device for encoding a sub-aperture image of a set of sub-aperture images obtained from a plenoptic image
First Claim
1. A method for encoding a plenoptic image comprising a plurality of microlens images, each microlens image formed by an associated microlens,the plenoptic image being associated with acquisition parameters of a plenoptic acquisition system with which the plenoptic image has been obtained,the method comprising;
- decomposing the plenoptic image into a plurality of sub-aperture images, andencoding the plurality of sub-aperture images using one or more encoding parameters, which one or more encoding parameters are determined-in dependence upon the acquisition parameters associated with the plenoptic image.

Abstract
The invention relates to a method for encoding a plenoptic image comprising a plurality of microlens images, each microlens image formed by an associated microlens, the plenoptic image being associated with acquisition parameters of a plenoptic acquisition system with which the plenoptic image has been obtained, the method comprising decomposing the plenoptic image into a plurality of sub-aperture images, and encoding said plurality of sub-aperture images using one or more encoding parameters, which one or more encoding parameters are determined in dependence upon the acquisition parameters associated with the plenoptic image.
The invention also relates to a corresponding device for encoding a plenoptic image.

20. A method for encoding a sub-aperture image of a plurality of sub-aperture images obtained from a plenoptic image,
the plenoptic image being associated with acquisition parameters of a plenoptic acquisition system from which the plenoptic image has been obtained, the method comprising; -
determining one or more encoding parameters and encoding the sub-aperture image using the determined encoding parameters, wherein the determining of the one or more encoding parameters comprises for each parameter to be determined; determining a subset of possible encoding parameters based on the acquisition parameters; and determining the encoding parameter to be used for encoding in the determined subset.
